Interesting point about nihilism, appreciate your discussion. I still identify as cynical in many domains, though I don't think of myself as nihilistic as the latter seems more absolute.

Re: things that really don't change, I'd say "until they do". Plenty of examples in history where the whole system switches to a different equilibrium point (for example as in "Inadequate Equilibria" book).

When I'm referring to cynicism, I'm talking about the difference between the mindset of "these will never change", vs "these are attractor points in the current social system, which all history so far have been used, but the system may have other equilibriums and solutions for which X=`the rich are not greedy`".

Hope that's helpful!
