There is no reason to hope, period. We have known the best version of capitalism (social democracy) for five decades due to the existence of the USSR.

Capitalism is irreformable. A system based on the pursuit of profit and capital accumulation cannot stop growing; it must commodify and securitize everything. Financial capitalism is an example of how nature, ecosystem services, the genetic code, or parts thereof can become private assets codified in law. Additionally, we have the rise of synthetic biology, AI, transhumanism, etc.

The problem of ecological overshoot will eventually be solved by eugenic means; the useless class that Yuval Harari talks about may well be a group to start with. The capitalist class tolerated social democracy until neoliberal theology took control. The Chicago Boys' first economic intervention occurred in Chile under the Pinochet dictatorship. At the same time, the majority of Western citizens lived in a kind of political hibernation while TINA was imposed on us and will lead us to Technofascism.
