The problem is the system. You can expect one or two persons to act rational, but at the scale of 100s, 1000s, millions, it's just crowd dynamics following statistical processes, just as the market itself is.
If we want anything to change, we need systemic changes to what behavior is incentivized by the world we live in - and I can not think of anything that would do the job other than abolishing or at least heavily restraining capitalism.
