Capitalisms’ unsustainable model of infinite growth requires something like imperialism to keep going, and even if you could point out alternative venues for capital acquisition, it’s still what people in power want, since it gives them more than just fuel for capitalism, but also more power. Countries and companies that do not rely on imperialism directly, most often rely in others that do. While it’s not entirely futile to discuss whenever that has to be the case in theorethical capitalist solution, it is the case in one we’re living under, and since it’s the ruling class of hyper-wealthy that make decisions about the worlds future and current state of affairs is result of those decisions, it is the system we have to deal with. Unless, you know, we bring out the guilottines and start over, but I don’t see much point in retrying capitalism to see if it won’t lead us down on the path to facism again.
