Herrnstein and Murray predicted in their seminal 1994 book The Bell Curve, Intelligence and Class Structure in American Life that US society would evolve with little change in IQ differentials between Orientals (Asians), Caucasians (Whites), Chicanos (Hispanics), and Negroes (Blacks). And that has happened as they predicted, except that Asians have widened their gap from Whites. That means you should read this book (click the above link for the pdf), and HEED its soundly mathematics-based lessons.
As my favorite biodiversity pundit Steve Sailer pointed out 3 years ago, America has evolved toward a CASTE society, in keeping with The Bell Curve's predictions, such that the more cognitive elite merged with the affluent (small wonder) and became ever more isolated from the cognitively disadvantaged (no surprise) who have ever less likelihood of escaping the mire of their condition. That might explain the relative inescapable, self-fulfilling sludge of ghetto and thug life in America's inner cities and newly spawned ghetto suburbs and exurbs. And of course, there is NO WAY the powerful will yield their power to the utterly undeserving, cognitively inept masses. As I have repeatedly pointed out, fully 25% of the US population has IQ below 85 and are too stupid to graduate from high school, while another 15% is almost as irresponsible, owing to terrible parenting, low IQ, and low ambition to achieve in a lawful enterprise. Unlike the problem of low ambition and bad parenting, from which one can with effort escape through personal striving, no amount of striving will relieve a person of the affliction of innate stupidity.
In other words, All Men Are NOT Created Equal.
So, what do you expect an enlightened society in an advancing civilization to do about the population's burgeoning ranks of stupid and irresponsible underachievers?
I have said that eventually, the elite must confess the condition of the stupid as interminable, proliferating, and deadly to civilization, and ACT intelligently and benignly to correct it. That means, in a nutshell, government must ultimately enact eugenics laws to outlaw procreation of stupid children (as a crime against humanity) and prevent unmarried people from procreating at all. Why? Because it goes without saying (and yet I'll say it anyway) that insufficient parenting equals bad parenting and single parents gravitate toward poverty which means their children get insufficient education in how to become an upstanding, responsible adult because the single parent constitutes such a bad example simply by having no spouse to share in the child rearing experience. And in most cases, the single parent bears a serious grudge against the would-be spouse, and typically denigrates the opposite sex to the child in such a way as to poison the child's thinking about loyalty of spouses and parents to one another. And NOTHING, absolutely nothing adversely influences a child more than the disloyalties of his adult associates.
Race statistician Richard Lynn revealed in his book The Global Bell Curve - Race IQ and Inequality Worldwide (2008) that The Bell Curve's analysis and prediction applied worldwide, not just in the USA. The bottom line: people are created UNEQUAL, especially in intelligence, some being vastly superior to others.
One obvious fact should seem apparent without saying - that intelligence, as measurable by standardized IQ tests, is the primary, NUMBER ONE, factor of importance in individual socioeconomic achievement and in building an advanced civilization. As much as proponents of Black Lives Matter, La Raza, and other race promoting groups hate to admit it, the USA exists because smart WHITE propertied men made it so. They crafted the founding documents and organic laws of the nation, and met as state delegates to endorse the Declaration of Independence and Constitution after lengthy heated debates of the merits of nearly every single provision.
The founders and American leaders who followed in their steps acknowledged the contributions of white men to fulfillment of the American dream of what I call "Liberty for Responsible People." Beginning in the 19th century, "Manifest Destiny" became the rallying cry for the US expansion to the west coast of the continent, an land acquisition effort that including the conquest or land purchase against England and Spain and Seminoles in Florida, France and England in Louisiana, Mexico in Texas, and Mexico in New Mexico, Arizona, and California, much other land north of those areas, against Britain in Oregon and Washington and other northern states, and against Britain in Hawaii and Russia in Alaska.
What is Manifest Destiny? It is the doctrine or belief that the expansion of the US throughout the American continents was both justified and inevitable, and it definitely challenges the notion that all men are created equal. Although ideally people in non-US areas should petition for statehood, foreign adversaries learned that they must either sell their claims to the USA or Americans, meaning the white race, would take it by conquest because it was their manifest destiny to have the land from coast to coast. Wikipedia says this about it:
------ Manifest Destiny -----
This was a controversial proposition for two reasons. First, idealistic advocates of manifest destiny like John L. O'Sullivan had always maintained that the laws of the United States should not be imposed on people against their will. The annexation of "All Mexico" would be a violation of this principle. And secondly, the annexation of Mexico was controversial because it would mean extending U.S. citizenship to millions of Mexicans. Senator John C. Calhoun of South Carolina, who had approved of the annexation of Texas, was opposed to the annexation of Mexico, as well as the "mission" aspect of manifest destiny, for racial reasons.[53] He made these views clear in a speech to Congress on January 4, 1848:
We have never dreamt of incorporating into our Union any but the Caucasian race—the free white race. To incorporate Mexico, would be the very first instance of the kind, of incorporating an Indian race; for more than half of the Mexicans are Indians, and the other is composed chiefly of mixed tribes. I protest against such a union as that! Ours, sir, is the Government of a white race.... We are anxious to force free government on all; and I see that it has been urged ... that it is the mission of this country to spread civil and religious liberty over all the world, and especially over this continent. It is a great mistake.[54]
This debate brought to the forefront one of the contradictions of manifest destiny: on the one hand, while identitarian ideas inherent in manifest destiny suggested that Mexicans, as non-whites, would present a threat to white racial integrity and thus were not qualified to become Americans, the "mission" component of manifest destiny suggested that Mexicans would be improved (or "regenerated", as it was then described) by bringing them into American 
democracy. Identitarianism was used to promote manifest destiny, but, as in the case of Calhoun and the resistance to the "All Mexico" movement, identitarianism was also used to oppose manifest destiny.[55]Conversely, proponents of annexation of "All Mexico" regarded it as an anti-slavery measure.[56]
The controversy was eventually ended by the Mexican Cession, which added the territories of Alta California and Nuevo México to the United States, both more sparsely populated than the rest of Mexico. Like the All Oregon movement, the All Mexico movement quickly abated.

Now, 170 years later, we know that a deluge of Mexicans and others from IberoAmerica, the West Indies, Africa, and Muslim lands have brought people into the land, and ultimately the electorate, millions of non-whites who do not share the religious or cultural ideals of US whites, and to a large extent resent whites just for existing and being generally superior to and more highly productive than them. As La Griffe du Lion pointed out in his article Cognitive Decline, the Irreducible Legacy of Open Borders (2005), it is civilizationally suicidal to allow hordes of stupid people to immigrate. As the population becomes ever less white (whites no longer are the majority race of children born in the USA), it becomes ever less responsible because of lower intelligence of the bulk of those non-whites in the population, and because of their 3rd world, truly alien, cultural values. Thus, the non-whites definitely constitute a threat to American civilization.
The big question: what will the great white hope, President Donald J. Trump, do about it? Will he show the leadership needed to block immigration of Muslims and dangerous or low-productivity people, and curtail the expansion and suffrage of the low-IQ population? Or will he stand by and watch the expansion continue apace until the stupid and irresponsible swamp the will of a significantly more intelligent minority at the polls?
And here's another pesky question. Does the USA still have the same "manifest destiny" it had in the 19th and 20th centuries to take other lands by purchase or conquest? The nation has had plenty of chance to snatch and keep the Philippines, Cuba, Korea, Vietnam, Afghanistan, Iraq, Kuwait, Germany, Italy, and Japan in the past century as the spoils of war. That's a lot of people to force to make English their native tongue. Maybe our nation's leaders learned a hard lesson from France and Italy, now swamped with non-whites from their former African colonies, and from our own travails as a consequence of permitting entry into the land of slaves from Africa and the West Indies.
It should come as no surprise that the average IQ of gene groups (such as in racial groups) correlates very highly with the value of productivity of the group. Richard Lynn and Tatu Vanhanen analyzed national IQ scores in contrast to Gross Domestic Product and found very high correlations except when the style of government (such as the Communist government of China) interfered with productivity value. See their paper Intelligence and the Wealth and Poverty of Nations.
Also see Lynn and Vanhanen's IQ and the Wealth of Nations (2002) and IQ and Global Inequality (2006), and Richard Lynn's Race Differences in Intelligence (2015).
I also recommend the analytical articles by La Griffe du Lion: The Smart Fraction Theory of IQ and the Wealth of Nations (2002) and Smart Fraction Theory II: Why Asians Lag (2004). These works by Lynn, Vanhanen, and duLion have angered politically correct liberal elitists who feel loathe to admit that average IQ markedly differs between nations or racial groups, and that even if they differ, they are not genetic in nature, and even if they are genetic in nature, they don't show one group as superior or inferior to another. They'd prefer that we all just shut up about the subject and pretend it doesn't exist so they can impose a guilt trip on anyone who claims one racial group or nation is superior to any other for purposes of building an advanced civilization. Too bad for them. Attention MUST BE PAID to these very important issues because of the demonstrably high correlation between intelligence and value to civilization in terms of productivity, value of productivity, and ability to provide for one's family, community, and nation. I personally believe American civilization's survival and advancement depend on these important principles.
The issue here has nothing to do with the skin color of Americans. It has everything to do with the average intelligence of racial groups, and the necessary measures for elevating that intelligence so as to enable the groups to have a higher value of productivity and greater worth overall to society and to the American Civilization. Skin color just happens to constitute a marker of average intelligence of the racial or gene group. Regardless of race, all Americans should aspire to elevate the quality and capability of their own gene group so as to maximize its value to the advancement of civilization AND to give its members a decent standard of living.

When it comes to elevating the quality of the gene pool, such elevation can only happen through slaughter of inferior gene groups or widespread benign eugenics programs. I prefer the latter, but history has a bounty of examples of the former when gene group leaders failed to do the latter. The time has come for national dialogue on this very important subject of eugenics and how to implement it across the land while it is still possible.
