> heavily homogeneous outcome

You can classify people along lots of dimensions including race, ethnicity, gender, religion, wealth, urban vs. rural upbringing, sexual orientation, introvert vs. extrovert, political leaning, and so on.

Your claim of homogenous outcome is based on how many of these dimensions? Just one?

Because of the immigration policies of the United States, people of certain ethnicities tend to be crème de la crème, for example, if you are from Asian countries you have to be in the top 0.1% of your country in order to immigrate to the US. As a result, if you take the top 10% of performers in High School they tend to have more Asians. To limit their advancement based on their race does not just punish them it punishes the nation by depriving the nation of its best brains.
