Just depends on if you want Equity or Equality in these systems. Imo I would want equity for the most part, but quotas should be income based rather than race-based, but still even then the system will be unfair for certain individuals. You have to be aware though that for these individuals they are already a leg-up based on their wealth to begin with (wealth is one of the biggest predictor of future success).
In an income-based system it would also appear as though asians and white people are discriminated against because they are the wealthiest ethnicities.
