The Chinese see multiculturalism as a sickness in the American body politic destroying a formerly-strong principally Anglo-Protestant US society. Racism keeps Chinese society strong and united against outsiders. 
Germany, Japan, US, and UK all dedicated 65-80% of their economies to aircraft, ships, and anti-aircraft equipment. Aluminum, crtitical for aircraft production, was thus as or more important than the more famous (Rise and Fall of the Great Powers) steel production. 
By the way, since we know contraception/family planning/abortion were not in common use until 1760 (France)/1870 (rest of Europe) and bastardry/cuckoldry rates were both very low, we can be confident this goes back to at least 1300 (less evidence before then). 
Of the big Euro socialist parties, the Italians PSI joined the Comintern, but was expelled for not expelling the minority who didn't want to. The German and British Communists were unable to take over SPD/Labour, respectively. Only in France did the major socialist party join. 
Stark observes that contemporary cults (as distinguished from sects, which split off from conventional religion) overwhelmingly recruit from the religiously-unattached upper stratum of society, and infers that Christianity probably did too. 
Immediate capital flight amid massive corruption from the ANC. Chief ambition of much of the new elite: opening casinos, assumed to be a license to print money. Shades of US states doing the same for tax revenue.
From "This Land is Their Land: An Immigrant's Manifesto". Mehta is a professor at New York University. America gave him a far better life than he could have had in India, plus a taxpayer-funded ticket into our cultural elite. And he despises us for it.
I did not know Rosa Parks was attacked in her own home in Detroit (by a black man). 
This is a very familiar map. Bet you could predict almost all of this with national IQ + selection + obvious adjustment for Afrikaners. 
South Korea keeping dependency ratios constant would require about a hundred million immigrants... PER YEAR.

Newspapers that optimize for audience engagement look like the NYPost or the Daily Mail. Think prominent pictures of scary black criminals, rather than burying nonwhite murderer's race like most papers. 
So what happened? Short answer is the things described in @charlesmurray's Coming Apart. First, Great Society welfare programs disincentived work among the left half of the productivity Bell Curve - you need to be above average to make real income gains from working harder.
This reflects poorly on university plans to attract Asian STEM talent to replace their white faculty. Ability isn't enough - you also need honesty.
This one is the fraction of people who report a lost wallet, with or without money. A consistent pattern of China doing much worse than other high-IQ countries is clear across these. 
Second, Asian immigration. Asian immigrants mostly compete with this group, and have driven an extreme (and much lamented) intensification of the education rat race in the 21st century. Restricting it (needed for political reasons anyways) would greatly benefit the UMC.
Mercer directly compares the ethnic transformation of America via Hart-Celler to the turnover of the state to the ANC in South Africa. Same process, just slower. She is very hostile to both Hart-Celler and Civil Rights. 
Raghavan refers to Rajat's generation as the "twice-blessed," benefitting from both the end of the Raj and the passing of the Hart-Celler act of 1965, which allowed them to escape their newly independent homeland and come to the US instead, where they quickly rose to the top. 
It is not just illegal immigration that is out of control; legal immigration is too. Immigration is in effect an imitation civil right, extended indefinitely to a group of foreigners selected arbitrarily and without regard to American interests. 
But was a simple partisanship analysis misses is that this is basically a consequence of the Mean Voter Theorem. Whites are still a supermajority of US voters, so the dividing line between parties is among generally leftish white ethnic groups.
