There is no excuse in this day and age for any American to go uneducated if they want to be. This is especially true of minorities as there are additional scholarships and opportunities available that white, Anglo-Saxon, Protestant males do not qualify for. No one needs to mandate quotas, they are a crutch. The races, sexes, etc. will never be equal until we remove the training wheels and make everyone equal. Equal opportunity, equal rights, equal responsibility. Where you go from there is up to you.
Mind you, I am referring to equal opportunity under the law not circumstances. Some people will have inherent advantages due to their family, upbringing, wealth, etc.
