There's no shortage of W-2 abuse in the US. You need N hours to qualify for benefits? Oh look, N-1 hours on your "full time" schedule AGAIN! Sucks to be you. But remember, we need full time availability & you don't get your schedule until two days before so good luck getting another "full time" job to fill in!
Gig economy isn't that different than the reality many people face working W-2. If anything it's more honest about the fact that there's no safety net and you need to keep working until you're dead. The idea of "having a retirement" is romanticized, but it's not going to happen for probably a majority of workers in the US.
