It’s a nice little game, but I don’t agree with the conclusion. I’m sure the POV depends heavily on the kind of capitalist system you live in, laissez-faire vs social democracy. As someone who lives in the latter, I think this is sufficient, but it hinges on solving the globalism problem (which might be unsolvable) and an educated public. If nations continue to compete with each other, it doesn’t matter if it’s a capitalist system or not, we’ll keep playing prisoner’s dilemma, I think. I’d also like to see the sequel to answer the question what we should do instead of capitalism.
