But thats the point. Your last sentence is the problem:

Investors proping up stuff by 20%, 401k and etf etc. regularly invest, investor drop out.

Who loses? 401k and etf.

Money was transfered.

Same shit happen to my company share: Price jumps 40%, company has to buy them because of employer benefits, I auto buy them, price falls back by 40%, what happened?

Investors extracted money out of the company and me.
