Let's not infantilize these poor and "desperate" drivers who don't know any better than to be exploited by the technocrats.
They were doing no better illegally sub-contracting with illegal sub-lessees of taxi medallions who themselves illegally forked out hundreds of thousands of dollars to wealthy medallion owners who hoarded them and prevented anyone else from legally procuring them.
The previous taxi system ( prior to the arrival of ride-hailing apps ) was thoroughly corrupt at every level. I hope thats not up for debate.
Immigrant new-arrival drivers would pay daily fixed amounts to illegally "lease" these cabs (on the daily) to those at the bottom of the chain of operators described above.
They were already "part-time" (well before the arrival of Uber and Lyft) and weren't afforded many of the protections the medallion issuing body put in place.
It was a thoroughly corrupt sham that the governing bodies paid little attention to and hand waived the illegal practices because they were (and are) themselves corrupt rent-seekers who were in bed with those interests they truly protected.
The officials knew it.
The medallion owners knew it.
The sub-vendors knew it.
The immigrant daily-wage-slaves knew it.
This is why Uber, Lyft and others were such life savers when they arrived. Everyone hated taxi cabs.
