There are no good guys among the main players, but the people who are not the main players mostly benefited. Workers got higher wages due to the infusion of cash into the demand side of the labor market from Softbank and KSA. The knowledge worker industry benefited from increased competition in the office space market. A few property owners benefited from selling their properties to a conman with virtually unlimited buying power. Now lawyers are benefiting and probably the personal security industry as well.

Sure, the people who chose to work for WeWork now have worthless equity, but that's always a risk when working for a startup, and they knew that going in.
