Tangential but it make me think, given the network effects and associated monopoly position of some FAANGs like Google or Facebook, it seems they could hire engineer to do nothing and still be vastly profitable. In fact, it would have the benefit or preventing top talents joining or creating a competitor. Therefore, how much is a "real" labor shortage vs a perverse side-effect of monopolies or a capital intensive hack of preventing competition? It's just an intuition from their monetized output from their profit centers compared to their workforce, maybe a dumb idea but I'm curious of what people than know more than me think of it.
