The problem with this analysis is that most people with a lot of kids are on some sort of assistance. WIC and CHiP are very common among big families. Most of the big, religious, conservative families I know are Catholic and I'm telling you they are collecting the government bennies. Meanwhile, the typical liberal with 1 or 2 kids doesn't use them (or at least not as many). And what's more, the libs' kids are more likely to go on to high paying careers. Of course there are lots of exceptions, but next time you run into a big, conservative family (more than 5 kids), take a closer look. Odds are, they're getting by with some of your tax dollars.
I'm all for big families - my wife and I raised 11. And we did it without government assistance. But honestly, if we'd have qualified back in the day, I'm not so sure my wife wouldn't have wanted to take advantage of the handouts (of course that would have happened over my dead or mangled body). But there's no denying, times were tough for us, and my wife, as the household manager, had to bear the brunt of it. I'm not blaming these families for doing what they can to make their lives less difficult. In other words, many big families are raising more kids who feel like the government owes them a living - the parents may vote pro-life, pro trad marriage, pro-2nd amendment, but philosophically, they're very often libs and they're raising little libs.
I’ll keep that in mind!
