In general, the US has boxed itself into a corner. It has largely deindustrialized itself (outside of weapons) and basically has the entire economy revolving around empire. There is no “Plan B”.

Even timid things like universal healthcare or public tuition can’t happen because it’ll make people less likely to join the military. It’s scary but if the US would actually commit to peace, the economy would sink to that of “undeveloped” economies. What actually exists, agriculture and the entertainment industry, that’s about it.
