Yes, but that's my point... the Chinese Dynastic cycle shows that good societies lead to corruption. Caesar wanted better and most sane/non-psychopathic people are not looking for power or wealth. So, it seems that the system is stacked against those who are honest/fair/truthful and stacked for those who seek power. As a comedian said: Those who want to be president should be exlcuded from being allowed to be!
What says "this time" will be any different than in the past? Am I any smarter/better than the past people who tried and tried? Deep down, that is why I changed from a hopeful guy into a "realist". Even in the book Learned Optimism, we learn that the optimistic mindset tends to think they have the power of control even when they don't. It's a delusion in itself that is rewarded in 3d "good times", but in the bad times, a more realistic/honest analysis tends to survive. For some reason, this realist/pessimist ME still exists now, but I still don't feel like I am much of use in this society that rather believe in lies like global warming or infinite growth (the economy- including the idiotic things Trump claims that will help the working class- which DOES NOT).
You are sort of missing the point: the point is to do what is right and decent and good and positive with no hope of recompense. That is, after all, pretty much the definition of STO.
