I intended this to be a thread about the benefits or harm a quota can bring into a business. Let's say board room meetings needed at least 40% of members needed to be asian or latino. What happens? I'm serious.
That depends entirely on the quality of the candidates. Questions like this cannot be accurately answered purely on racial quotas.
For example, let's say that you want to stock that board with African Americans who have some experience with running a business of any type, without particular care for quality. Limiting it to just the ones who have been upper management or even the guy in charge, you still would be swamped with candidates. Unfortunately, due to the nature of the realities of discrimination that African Americans face and the self-fulfilling prophesy that is the stereotype of them being criminals, most of those people would be gangbangers or minor drug lords. Which, in turn, is only going to make the stereotypes and discrimination that African Americans face
worse instead of doing anything to improve their lot in life, since most people will see what they think is objective evidence that the stereotypes are right.
It can also be used to create an unofficial ghetto with even worse discrimination. A simple quota system, of X black to Y white, is the underpinnings of desegregation... and also why, in quite a few communities, it was an epic failure worthy of a Greek poem. After all, how can you say you're managing to desegregate if the whites simply leave and force an even worse segregation than existed before?
A quota system simply focused on numbers of one group without focusing on also improving the quality of those numbers is simply doomed to fail. Assuming it's not actively sabotaged like in the case of desegregation, it's still going to run across a problem that fields in which certain minority groups simply don't have the numbers or high amounts of people with the skill, adding in a quota system without addressing the underlying societal problems that help create that lack ultimately only reinforces those societal mechanisms because it forces companies to accept substandard employees just to meet the quota and, in turn, has those employees unwittingly be evidence in favor of the original discrimination the quote sought to address. And, in turn, increases discrimination against those people by reinforcing any societal negativity towards them in members of the more dominant groups who might otherwise have been predisposed to helping them do away with the discrimination.
So, to answer your question purely as it was asked and without considering any other efforts to fight discrimination: It increases discrimination and makes things worse for everyone.
That's why we cannot discuss the topic without also discussing broader issues at play.
