Are we not talking about income inequality? Fact is hard currency is finite, perceived wealth or value is something else entirely.
Income is typically tied to hard currency.
When you make money in the stock market, you invested in a business, one that would supply a goods or services (or a derivative), of which requires taking someone else's money in exchange for that good or service.
There is no such thing as doing "everything right" a capitalist society is a zero sum game.
You only make money by taking it from someone else. Sure the reserve can print more money but that only leads to currency devaluation on a macro level which on a whole reduces purchasing power of the society.
You can't really address income inequality without fundamentally reshaping society.
