It is easier to imagine the end of the world then the end of feudalism.
I kind of like the story of how Malthus had his theory of societal collapse because he couldn’t imagine a better system then mercantilism. That societies would rather collapse then to end their colonial monopolies.
I see a similar theory today with around depopulation, that as society gets older and relatively fewer working age people there are, that society would rather collapse then we find a better system then Capitalism.
What system works better when you have a very large number of elderly people who want to retire and very few young people to work?
