The first thing that came to mind was sterlization (if only). Then they could get as drunk and stoned as they want and not have to worry about that pesky baby.
But then, that's the quandary, isn't it? We expect people to take responsibility. Then they don't and we make excuses for them..."well, the oven wasn't ON"..."they're only kids themselves"..."they had a rough childhood"..."the racist angry tea-partiers are to blame"...blah blah blah.
(OK, that last one I threw in just to stir the pot)
All that feel-good, hippy-dippy garbage from the 60's has come home to roost (to paraphrase Rev. Jerry) in our culture.
