correct, and that is exactly what the quota system is all about, jobs and making a black middle class - you must employ this many blacks in certain positions, this many women etc.
Standards will slip because that quota person hasn't always had the precious advantage of the white, education etc
That middle class blacks son or daughter however may then get that education.
That's why it takes generations
You can't do it too fast or you completely fudge up the country but at the same time it can't be too slow as people won't wait.
The speed is the key and the timing
Unfortunately there will be serious losers in this system and yes the best person will not always get the job.
However when you move from a system where you can't go to a certain beach because you are black, you need something to address the balance
