Here's part of the problem. You're stereotyping them as lazy addicts. How do you know if it's a can't pay, or if it's a won't pay? You're blanketing a problem that's going to leave thousands without water with a statement implying it's their fault for buying drugs and booze? What authority gave you the statistics to prove such a claim? Or is it a fiction made up to make yourself feel better about it?That is terrible but what do you do short of taking ownership of the kids away from the parents. If parents want to spend their $ on drugs and booze instead of their kids there's not much you can do about it.
Yet these issues will happen regardless of breeding laws, if you're talking about accidental pregnancy. Actually, that's a pretty big issue you'll have trouble overcoming. How do you deal with it when a unsanctioned couple has kids anyway? Are the kids left to fend for themselves? Is that fair? Should the parents be forced to abort it?But what about all these people who pop a baby by age 18? Now they've got a family to provide for and they have zero education and limited opportunities from a self made disaster.
