Fact is, a Japanese kid in an American school does better than a Japanese kid in a school in Japan. Same thing for any ethnic group you can name, except for a particular ethnic group that cannot be named.
Since that ethnic group has an average IQ of 85, it is impossible to raise their scores. In the name of "equality" however, it is possible to cripple the high-achievers and drag their scores down.
It's not fair that some people are more successful than others, you see.
and this is why liberalism exists... to punish excellence and artificially prop up the weak.
I’d argue that above average kids from whatever country are the ones who tend to make it over here.
But I agree with your larger point.
