Aaron Benanav in The Guardian:
The truth is that Uber and Lyft exist largely as the embodiments of Wall Street-funded bets on automation, which have failed to come to fruition. These companies are trying to survive legal challenges to their illegal hiring practices, while waiting for driverless-car technologies to improve. The advent of the autonomous car would allow Uber and Lyft to fire their drivers. Having already acquired a position of dominance with the rideshare market, these companies would then reap major monopoly profits. There is simply no world in which paying drivers a living wage would become part of Uber and Lyft’s long-term business plans.
Only in a world where more profitable opportunities for investment are sorely lacking can such wild bets on far-flung futuristic technologies become massive multinational companies. Corporations and wealthy individuals have accumulated huge sums of money and cannot figure out where to put it because returns on investments are extremely low.
