The establishment's theory of race differences in socially valued metrics is that this is due to "systemic racism", a kind of Marxist conspiracy theory where the dominant group (Whites) keeps other peoples down.
There are clear testable predictions from this theory. In places where racist, White people have more power, outcomes for non-Whites, especially Blacks and Hispanics should be worse. Recall that the US demographics by county look like this.
Of course, Republicans are racist in this theory.
Thus, the theory predicts that in these areas of the USA, Blacks and Hispanics should be particularly worse off compared to Whites. But the exact opposite is actually true. The race gaps are smaller, not larger, in Whiter and more Republican areas.
The above figures are for test score gaps, but the same holds true if we look at social status gaps. Here's some maps of race gaps in social status.
So we need another way to explain the variation in social status gaps. Well, it's easy. Test scores -- academic achievement that mainly reflecting intelligence -- explain why race gaps are smaller and larger in various locations. Meritocracy works.
It gets even worse for the theory. It turns out the effect of White population share and Republican vote share are interactive. The areas with the smallest race gaps are the ones with the largest White populations and the largest Republican vote shares combined!
There we have it. The Marxist conspiracy theory that is the go-to explanation of race relations fails when we look at county-level variation across the United States. The predictions it makes are exactly opposite of reality. If anything, it seems Republican Whites are good for minorities.

New study out: Systemic Racism Does Not Explain Variation in Race Gaps on Cognitive Tests
Can Europe learn from Ghana? Buried on Wikipedia is a 3 sentence part about how Ghana deported 20% of the population -- 3 million people -- all the non-Ghanans. And it only took 3 months. The "Ghana Aliens Compliance Order" (GACO)
This website provides the history. It begins, of course, with economic migration since Ghana was the gold coast. In fact, these migrants were going into a British colony, probably for the usual reasons of wanting to live under European domain: rule of lawand prosperity.
European rule eventually declined, and just after they left (1957), the economy goes bad. At least, so they say, but it doesn't look that way until 1970s by GDP stats.
In Germany, non-German students (anyone with "migration background") get lower grades and test scores.
Due to their politics, teachers are expected to have some bias towards girls, minorities, low-SES etc. students. So do they? The authors find that, yes, they do.
New Dutch results on immigration. Sobering as usual. There are 3.7 million foreigners in the Netherlands.
One can calculate a given person's contribution to the state budget by adding up all their contributions (revenue) and subtracting all of their costs. Doing so gives a net contribution metric. Dutch people are c. net 0, and the others groups net negatives.
There's a lot of variation though. Numbers for the first generation can be very positive or negative. It's easier to get very positive values because many people arrive after having finished their education, so begin working immediately. Many of them leave before pension too.
Many of you have seen this figure. A pessimist's favorite. A massive innovation decline starting from 1880 or so.
It fits suspiciously well with the onset of dysgenic fertility in NW Europe, or at least the UK.
However, does this really work this way? It's based on a 2004 book called The History of Science and Technology that recorded significant events from 3000 BC to 2003 or so. But what if the author missed newer stuff that wasn't recognized as important yet?
