It's not that easy if more and jobs are like that. It's pretty condescending to tell somebody who doesn't have much choice that he should do something else if he doesn't like it.
Work at McDonald's or drive Uber? Drive Uber because it's cooler than making fries. Make fries because there's a matching 401k program at McD's. These drivers have a choice.
If Job 1 pays $100/day and Job 2 pays $110/day, the person should choose Job 2. When other things come into play like fulfillment, entertainment during the day, interest in one's work, etc., the choice becomes less clear, of course.
The big thing for me is that these drivers have costs that aren't immediately realized, like the wear and tear on their vehicle or the lost compounding benefit of matching funds in a 401k that they could find at another job. They continue to make an economically poor choice because these costs are easy to forget/ignore/be unaware of.
