Is There a Distribution Problem in Capitalism?

There's no doubt that distribution is a major problem. That capitalism contends with imperfectly at best. But the idea that capitalism is more prone to that distribution problem than any other system, I don't believe that to have been demonstrated at all. And I think that capitalism is actually pretty good at self-destruction, except when that's interfered with. So fair enough for the critique of capitalism. The issue is, do you have a better idea?
