Let's see here. If affirmative action is here forever it will means that the lawmakers believes in appointing people according to race and not skills.
Let me tell you something. People are a lot like fairly 'immiscible' liquids. Cultures varying in that characteristics to a certain degree. English people may blend better with Afrikaners than Black people may blend with Chinese, for instance. Now when you just leave everyone to live there normal lives, people (like liquids) seperate into their respective 'pure' cultures. But varying degrees of cultures stay behind 'mixing' with other cultures. It means that you more likely to see three small companies, one Indians, one Afrikaners and one Black than one company having an Indian, Afrikaner and Black boss.
Now the government is constantly shaking us to make us mix more. But when they see that it doesn't always work, because we just settle apart again they start to try to boil us. That is because gases mix much more readily than liquids.
Now the government can try to support Black companies much more to start building their own enterprises, but it's much easier to just leech permanently. Going against nature.
