if the threat of revolution gets great enough that they're scared for their own security they might give something up of their own volition but I wouldn't call that "willingly."
Yea, that's pretty much what I meant. A stable country is what enables them to keep their wealth. They know that if things get too bad, their safety is at risk.
another bad thing is that we're cooking the planet in the meantime.
Well, duh, but that's a completely different, and more concerning problem. At least with poverty and income inequality, the vast majority of the electorate are in "general" agreement that these are pretty big problems, they just have very different philosophies on the solution. With climate change, I'm not even sure we have a majority that believes it's even a problem, never mind a significant one.
