Some recent commentary about leftist opposition to the emerging economy:
The sharing economy tends to do an end run around regulators, and to challenge entrenched business interests that benefit from a cozy relationship with government. It upsets everything if Airbnb lets people find lodging that isn’t a hotel, or Lyft, another ride-sharing service, lets them find a ride without sticking their hand out and hoping for the best.As a disrupter of sclerotic practices in the economy and government, the sharing economy is predictably the subject of a furious regulatory and legal counter-assault. Uber has been a target in cities around the country, and abroad.
