An excess of non-producers is not actually a problem in a capitalist society. They die on their own, by their own choices and actions (or lack thereof).
It is only in a socialist society that an excess of non-producers is a problem.
Honestly, I complain about a lot when it comes to government (and I reserve the right to continue to use free speech to challenge anything), but there are actually very few things that I'd be willing to take up arms regarding (far fewer things than our founding fathers, that is for sure...my tolerance for totalitarian government is far greater than theirs was...I can't say I would have been for the Revolution). This issue might be one of them, though. If the US got to the point where the federal government controlled my right to have a kid, then the federal government can go fuck itself. I am actually quite confident that it would never get to that point, thankfully.
