I think American "left" and the Left everywhere else are entirely different things. As a leftie in the UK, I do not recognise the NYT as left at all.
Unions always enforce expensive, outdated work. The taxi cab unions fought Uber and Lyft, a vastly superior taxi system, all to prop up an existing outdated system.
Vastly superior for who?
Good things won't last forever. The taxi cab unions are already fighting these companies back in many cities.
They kind of remind me of the record industry and file sharing in the 90s: fighting technology, so they can keep their outdated and expensive system in place.
Most unions are like this. As another example, they will fight automation and force companies to hire multiple, overpaid workers, for a job that can be done by a single person. This only holds companies back and puts them at a disadvantage.
