Completely naive view of the situation, or you are just too young.
You don't need be 500k in debt to get started for uber as you needed to get a yellow cab medallion
Once you made that decsion (to mortgage you house to get a yellow cab medallion), you are bound to that job as a serf....
Modern day serfdom, that's what the yellow cab medallion system became to the large cities.
the only way out, was bankruptcy, or hope another person will pay just as much for that medallion. Often local mafiosi types were entangled with the system, and you had to deal with them as well.
Please, lets not glorify the pervious system, as it was much worse.
We can work and make this new system better, and force the large corps to provide more (benefits wise), but returning to the old medallion system is two steps back.
