In my eyes, the problem is that succeeding in capitalism has almost nothing to do with brains, and almost everything to do with luck and ruthlessness. Workers are the ones who produce value, so any profits that a business owner is able to extract from a business is value that is stolen from the worker. The most successful capitalists are the ones who are most willing to exploit other people. If it becomes impossible to become exceedingly wealthy, then we remove the profit motive on exploitation, and everyone is better off.
