This has been the case for all of human history. The solution is that the economically unfavoured do not reproduce, and the favoured do. We are all the children of European tribal leaders, kings and nobles thousands of years ago. Follow this approach, and the problem disappears in one generation. Enact some kind of wealth redistribution or welfare system and the problem will continue to grind on.
