gollark: Where are the actual incentives in anarchism? It seems that you basically just expect people to embark on giant construction projects and give resources out of the goodness of their hearts or something. In capitalism you actually have a decent direct reason to do that - your company can make more profit if it makes a new silicon fab or something, so you'll get money yourself, and you can get resources from other companies because you both get benefits for trading that way.
gollark: Well, that's just wrong.
gollark: You could do a *bit* of poor-people-saving.
gollark: You could... profit off the crash, trying to mostly take rich people's money, and then donate your newly obtained wealth to the poor?
gollark: If you actually believe that, you could make money off it when it happens.
