The problem of infinite growth
There is a problem of infinite growth you all seem to forget. Capitalism cannot survive without exponential growth. The solution to that is imperialism, and and infinite expansion of humanity. Ignoring the fact that we can't stop climate change, in the future we will have to expand the extraction of resources (not out of real necessity, but out of capital accumulation). This will take us to outer space and beyond. There is just one small thing you all seem to forget, growth consumes all of our resources. We have 20 million people dying of poverty a year simply because we would rather let our resources go to waste than spend time distributing them properly. (We waste much more food than we would need to stop world hunger, and that is just one example.) When the only possible solution to our problems is putting all of our resources towards infinite growth there is nothing left for putting towards humanity itself. You will be stuck in the same endless loop forever. That is not progress, but hell itself.
