The world is ridiculously overfull and Americans didn't make it that way. And the rest of the world is headed for rapid population increases to make it much worse. Americans shouldn't have to suffer for that; we've got a little space left and we should guard it jealously. And just try driving in any major prosperous city at rush hour or riding the subway. Or renting an apartment in SF or NY. We can't expand housing or infrastructure in those cities and we're admitting millions of foreigners overfilling them even further.
