You asserted that Robinhood is evidence that "labor" in general has access to "rich-get-richer" mechanisms. My assertion is that this assertion is not valid. The rich-get-richer mechanism in question is investing pre-existing large amounts of money in investments that are more or less zero risk, specifically from the perspective of the investor's personal livelihood and well-being. This is simply not available to most people, even if they do have access to zero-commission fractional-share trading on Robinhood. Also, "labor" covers a large amount of people, of whom a very small subset are Robinhood users, and of whom an even smaller subset are legitimately successful traders, as opposed to one-off financial market lottery winners (who are themselves a small subset of all users).
