The article brings up reasons why blacks have lost out, they were discriminated against. Read the article or read the stuff that I quoted.
The article doesn't mention quotas and neither do I.
I think for historical reasons blacks today find themselves in a position of massive disadvantage and that it is hard to get a level pegging.
I forget where I've heard it from, but image 4 white people playing monopoly, they go around the board 4 times, buying up property, accumulating wealth, and then 2 black people come along and ask if they can play too. Sure say the white folk, they let the blacks join in but don't restart the game. The blacks start off with no property and just the start off amount of money.
It can't be racist because all the rules are the same for everyone right?
But who do you think is more likely to win the game? The white guys or the black guys?
