Earlier quoted context omitted.
Because these companies are still finding enough labor after lowering what they pay out drastically. It's the market in action. You're right that as a society we have a duty to step in with policy here, as we do with minimum wage, but this isn't a violation of "first principles".
That's when I thought the economy was doing really great and unemployment was all time low. But wait people want to work for below minimum wage? Something is broken
I'm not trying to disparage people, but without some level understanding of economics, it's not obvious that whatever rate you receive is not your 'wage'. These gig jobs don't pay wages, they pay something closer to a fee. Maybe it's more like rent. Somebody else can comment on the pedantic differences. Point is, the relationship is skewed in favor of the party doing business, not the party providing the service.
So what? This is capitalism, you have the freedom to seek other opportunities elsewhere. Hold up. If this is your business model, you are dependent upon the current wave of de-regulation. What are you going to do if/once the pendulum swings the other direction? What happens if minimum wage ever becomes something reflective of a living wage?
These gig jobs posit themselves, subtly, as a 'side-hustle'. Something which shouldn't have to exist, but does, simply due to the lack of well-paying jobs for those without advanced education.
