I've heard of the 2-kid limit/cap on welfare benefits, I like the idea.
Or.... I know people on both sides of the aisle will complain... but I love the idea of offering every child (in counties with very high teen birth rates) an elective option of taking the shot for cash. You know... $1000 cash, and you get a ten-year birth control shot. (Do they have those? I know of the 5 year thing...)
Offer it to anyone 12 or older. Some will opt for it, some will decide against. completely voluntary. Add up the costs of 10,000 babies... from pre-natal to birth to many years of govt benefits... vs a 1-time shot.
I bet the productivity of those counties would skyrocket too... more kids going to college and sending $ back into that community, starting businesses, etc. Completely voluntary and very cost effective.
I know, those that don't live in reality will say "Oh, we shouldn't have to, screw that, tell people to stop having sex and getting preggo", but in reality, that won't happen.
