While the dynamics described in this article are accurate, the real cause of runaway inequality is not capitalism itself, it's the monetary system. Without infinite money printing and centralized issuance, wealth would not artificially compound in the hands of the rich ad-infinitum. It would still be possible for most people to compete against the rich because the markets would be a level playing field. This is not the case currently because the rich essentially receive huge subsidies in the form of predictable, almost risk-free capital appreciation of their high-exposure assets propped up by money printing and also via huge government contracts awarded to their companies. With these neverending streams of passive side income, it's impossible for newcomers to compete against incumbents as the incumbents can afford to run many of their businesses at a loss... Something which newcomers cannot afford to do.
