I think what a lot of Americans don't want to admit, as imperialists, is that our relatively good quality of life was because we grave robbed and enslaved people for it.

When people say that there's economic booms after wars - that's not like, from no where. That's from all the dead bodies and looted countries. We sifted through pockets and took their change. And that's not better for growth or the economy than just keeping everyone alive btw - it is far superior to just keep everyone alive, educated, and fed and they will produce goods for the economy without sacrificing local people (eg Irish potato famine). Like healthy societies don't engage in war.
