It's the self-selected group of people who have chosen it. Much different than a random sampling.
Uber drivers have pretty clearly chosen being a contractor, and if you listen to them they say they like the freedom - require it even. You can usually moonlight as a contractor without permission from your primary job.
Other drivers, driving as full-time employees, have obviously made their decision in the other direction and seem happy.
It seems wrong to tell either that they must change.
Some drivers may want this. Others might not. I have a hard time believing any generalization about such a large group of people.
