Don't gig apps largely create jobs that didn't exist previously? E.g. we used to have a few people employed in pizza delivery and taxi driving; now we have delivery for a much wider variety of restaurants, and taking an Uber/Lyft is far more common than taking a taxi used to be. So I don't see traditional jobs being cannibalized for the most part. Alternatively, wages are low in gig apps because so many enjoy the flexibility that the apps provide.
