I'm struggling to fully understand the point. The author states that accumulation of capital led to this economy where investors are almost forced to lose money because they don't have enough good investment opportunities. That implies there is a transfer of wealth from those investor to the workers in those money-burning companies. The author also states that this probably won't work for Uber to gain monopoly status anyway. This really sounds like a redistribution mechanism naturally occurring in the market itself. Then the author pushes for this to be regulated out of existence. What am I missing?
