This article just won a Godwin point: basically if only the rich whites are taken into account, the American school is better than the Canadian one ... sure, that's a nice way to evaluate an education system ...
Yup, you must be right, there are only rich white people in America. I was commenting that although the vast majority of European countries and also Canada tend to have single-digit percentages of visible minorities compared to 34% of the United States, they are often quick to accuse the U.S. of racism, or fail to understand the implications of a truly multicultural society. Germany has 6% of its population with ancestry outside of Europe, yet there is this "Integrationsfrage" that gets a more lip service than you can imagine. Basically, it is encouraging a lot of countries quite literally to look in a mirror before judging. The U.S. education system has failings, but its populace is fundamentally different what the above commenter was trying to compare it to.
Well, the problem with minorities in US, Germany and everywhere else, is that usually they are immigrant, poor, living in bad neighborhoods, so yeah, they will pretty much score lower at school, have much more crime, etc. But not because they are Mexican, Gipsy, Turkish, but because they are poor immigrants.
