isn't it pretty hard by now, BTW? Look at all these negative return rates in huge banks.

Look at insane bull markets last couple of years. Rich people don’t have their money just parked in bank accounts. They own real estate, land, stocks so they benefit greatly while majority of population benefits very little from ever higher highs in the stock market. Basically rich people control most of the stuff which generates passive income without the need of labour which causes ever widending gap between the rich and everybody else and shrinking of middle class.
