Last night a friend asked my opinion on the immigration debate. I said something like this:
Yeah, the damn Mexicans are taking our jobs, but that's all just a distraction from real problem: all those people out there giving birth to babies! Thanks to all those parents, millions of babies enter the country every year, and when they've grown up most of them end up wanting jobs!
If the conversation had gone on, I might have mentioned that the babies who don't eventually take our jobs end up on welfare instead. And if I'd had the statistics on hand, I might have been more specific: over four million babies are born in the U.S. each year, as compared to about one million immigrants. Maybe the Minutemen should start blocking the maternity wards instead of the borders.
(Note: I don't claim to have originated this particular reductio. I think I saw the same point made on another blog a few years ago, before the immigration debate blew up. But I can no longer remember the source.)
