Affirmative action biasedly lifts up minorities over others. It looks noble on the surface, but realistically creates more of the same problem.

When I applied to college, I (and all of my friends), knew that ticking any non-white ethnicity box on the application made you more likely to get accepted. I don't know that any of us did, but it was very well known that you could game the system this way.

It made acceptance into college less about your academic merit and more about your ethnicity (or ability to use ethnic bias to cheat the system) - aka, more racism.
