I don't know what you mean but trying to have ratios and make underrepresented groups make a bigger proportion in things, means that for the group that they are trying to cut down on, the requirements/standards are for getting in are higher, space doesn't come from nowhere, and the system is no longer merit based, if you're good enough as they say you have to be, you still aren't.
More specifically, I am talking about colleges in America. For certain colleges (the high ranked ones actually) as they already have a high Asian population, it is harder for Asians to get in then everyone else, they have to be above the requirements for everyone. I'm saying this as it personally affects me as I'm Asian and have to put it on all legal documents. I've gotten in my top school so I have no worries about this rn, but it's a fact
Let's say you have to be 85th percentile to get in, you would have to be 92nd percentile to get in if you're Asian, let's say you have to get a certain score on college exams to get into a school, no you have to get EVEN higher
