this is a bad take 1. the us had open borders because they could offer land to people coming in, it had economic benefits for everyone involved. nowadays, EVERYONE wants to get in, especially actors with bad intentions, and as was just shown in europe not even five years ago now, open borders are a terrible idea with long lasting consequences. 2. economic growth does not simply derive from a larger population, there's a balance between population size and the economic prosperity of each individual within that population, to tip the scale so absolutely in only one direction completely destroys the scale itself 3. geopolitics are not so black and white. it derives complexities in more areas than just population, and the US does not have a small population, nor do its allies
