Does it matter who entrepreneurs are? They exist to serve society by providing new products and services that didn't exist before. We pay the winners well to motivate them to do that. It's not charity for their own good so it doesn't matter if there's bias in choosing them or some classes of people are excluded. It's not for them.
You also need to consider the opportunity cost. If more people were willing to take the risk of starting a business perhaps that would lead to a more prosperous society.
