Why can't any of these incumbents work with innovators to ensure happiness for all and not just enriching themselves?
I don't know if you've ever been to a medallion auction but they went for over a million dollars each in Manhattan before Uber came along. Most of the medallions were bought up by holding companies that then leased them out to drivers who paid up front and had to hope they made enough money that day to cover the fee. In San Francisco, I remember a driver told me that his up front fee was $100-200 per 8 hour shift depending on the season - that's over $100-200k per year ROI and SF's medallions were a fraction of the price of NYC.
I seriously doubt many lives were ruined by the fall in value of taxi medallions. Very few are owned by actual drivers and that's where all the money is.
