I won't recount what recently happened to a friend in Milwaukee. It was an unpopular story (because the ripoff was Uber-based, and not the traditional taxi).

There's bad actors in every industry. I have found that industries that get "entrenched," tend to breed the most bad actors.

If anything turns into a "pseudo-monopoly," expect the grifters to start popping up. They'll figure out how to game the system.
