The truth? In Massachusetts at least 70% of the drivers working for Uber and Lyft were doing it illegally thanks to the loose background check and because these people were willing to accept being ripped off by these companies. Once they tighten up the sign-up process and disabled those accounts, the ones left were mostly Americans and other people with work permit. What Uber and Lyft didn't expect was that these drivers are neither working 10-12 hours a day, nor willing to risk contracting the virus. They'd rather stay home and collect their checks from the government.
The perfect storm.
