Because there are people being left behind. Productivity per person has increased massively over the last half century, yet income per worker has been stagnant unless you break into a few specific contexts. This doesn't appear to be a necessary part of innovation as PG and others claim, but rather is a reflection of concentrated wealth's ability to restructure the market and even the legal system to better serve those concentrated interests. This is the pernicious problem we have to fight. It is in no way somehow exogenously necessary for people to have half billion dollar yachts in order to advance the life of the typical human. "Markets measure merit" is a lie told by those best positioned to control markets to manufacture their own "merit."
