Life, liberty, and the pursuit of celestial bodies. “America’s done expanding” is the implicit rule. Our nation’s finished cooking, and the future looks like this forever (or maybe just a little smaller). It’s impossible for us to grow, and if it’s not impossible it’s bad. While we almost never discuss it in this way, everyone knows our country is as big as it will ever be. But when did I pick up the idea? Who taught me this, and why? More importantly, is it true? Why can’t, or shouldn’t, America grow?
