Even worse is that America out of all the developed nations has an absurdly low population density. With the sheer amount of agricultural land and natural resources they have, they could support 100s of millions of more people if they were willing to use it effectively instead of wasting it on single family zoning, cars and livestock.

Even with our current wasteful production strategy, we throw away enough calories to feed an additional 160 or so million people per year. It's such a non-issue but the fact that the poster is worried about it illustrates the drive to protect our walled garden from the perceived undeserving.
