That's not much of a problem, it just shows how capitalism is not a sustainable system on its own. It shows that capitalism is fine and dandy in some contexts, in others, it doesn't work well. So the conclusion is that a mixture of systems need to be in place: for example, strong social programs could take care of people while they are growing up or begin to fall out of the system, and capitalism can always step in on top of that, or as an alternative even.
