FDR seems like a very odd example of compassion based leadership. The US was literally killing millions of people under his watch and he setup the Manhattan project which culminated in dropping two atomic bombs. I won't even make a moral judgement on any of that, it just doesn't seem like an example of the a cooperative and peaceful society that you're talking about.

Yeah, you can stop calling me a fool. Like I said I'm not making any value judgments. If anything your example disproves your own point. The reality is that humans are not harmonious by nature at scale and the people in charge are always going to be powerful and practical ("amoral" in your terminology). If they weren't, the systems would collapse or be taken over by a competitor who is more effective.

Edit: we're done here. You obviously can't have an intelligent and respectful discussion.
