I think the disease is actually political systems which dramatically misalign the well-being of the rich and the rest of us. If you fix that, everything else will fix itself through much more long-term political decision making.
You have to align well-being of "the rest of us" for us, against the will of most of us, though. Say "carbon tax" out loud, and most regular people will shout you down, because it'll make their gas prices go up.
