I don't recall the exact law offhand, but from what I've read, in the United States, any 'Affirmative Action' process that actually does use the ethnicity of a candidate for a position (school, job, or other) is in violation of the very law which supposedly supports them. The purpose of the law was to ensure that NO ONE got any special privileges. And I vaguely recall reading that, when said law was passed, there were arguments about whether or not it would be used to create just such a 'racial quota' system as we have today.
Naturally, the politicians passing the law said <paraphrase>"Oh, no, that will never happen!"</paraphrase>
And while the 'diversity' issue is getting played out, consider the question of what kind of diversity is valued, and what kinds aren't. For example, picture the reaction of most (US) college instructors in anything from Political Science to English Literature if you were to try taking the traditional 'conservative' ideological stance in their presence...especially in their classes. Is biological diversity (ethnicity or gender) worth anything if it's accompanied by an ideological homogeneity?
The 'Affirmative Action' quota system was indeed declared unconstitutional by the supreme court; however, affirmative action policies today are no different now than what they used to be.. Colleges and businesses still hire people based solely on race in order to accomplish their diversity goal. Some state courts have actually declared all forms of affirmative action illegal (I think the specifics are in my essay).. But the fact remains that some schools in the United States will enroll less-qualified students over students who deserve to attend the school simply b/c the school wishes to become more diverse.
What if the poor have 9 A's at GCSE and are super intelligent? Shouldn't they get a shot at a career they might do better than some shithead rich kid?
Statistically, what is the probability that poor students will do well in school? Most poor kids are not intelligent, and care nothing about education. They are not to blame.. More than likely, they grew up in a bad atmosphere by parents who did not care about education, and so quite naturally the children did not find education essential.
And so, the people of low class are stuck in society... Exactly as the way it should be, so that the rest of us can enjoy at least moderate wealth.
