On the contrary it almost always works. Force the quota of women, gays, blacks, Jews, poor etc. to zero and the privileged group will spend almost exactly no time considering the fact that there may have been someone more qualified that could have bumped them imperceptibly down the ranks if that quota wasn't enforced. They'll not even notice after decades of this.
Just make sure you don't do it to anyone, like straight, white males who have the political strength to resist it or you'll never hear the end of it.
would you be okay with quotas in sports? music? movies?
something like "30% of olympic 100m finalists should be allocated to minorities" etc?
I've seen students with laughable grades (no, I am not making this up) get into medical schools, because they are from underprivileged group. Would you be okay with them performing surgery on you?

Quota system is a very dangerous game to play - it usually goes downhill quickly, even if the intentions are good and even if people who run it are super competent. There are numerous other ways to help the under privileged.

History has lots of people from the privileged class who ended up working to improve society as a whole. Bill Gates is great living example.
