I’m not sure what wealth is. Let’s use the term value i.e. when raw materials (eg ones and zeros) are transformed to a useful form (eg a computer program). The programmers at amazon create value and then use most of their wage on subsistence eg supporting their family. The board of directors buy, ultimately through a chain of command, workers who are able to make more value than they consume in wages (otherwise no one would hire her). They also use money for subsistence, but they consume part of their accumulated value on creating more value. The programmer takes risks in agreeing to work, because if he is layed off then he won’t be able to provide for her family. So how can the programmer also use value to create more value? Entrepreneurship, ie being paid based on the profits she generates, rather than what the board of directors is willing to let go of. Or perhaps investment, which ultimately means profiting off the value creating labour of others in a indirect way.
Jeff Bezos is not owning much money. Warren Buffet id not owning money. Neither is Bill Gates. Money is just one asset you can own and most people hold very little of it.
