I contest your first implication. Even if your time is worth more than what Uber pays, driving for Uber might be the best way to make do with the resources and situation at hand. It might be more expedient for a recent immigrant to obtain a licence and a car, rather than the retraining and education necessary for a higher paying job. Indeed, that individual might not even have the prior education or language skills as of yet to obtain better employment. The claim that a full supply of labour implies the worthwhile tradeoff of an individual’s time does not hold up under scrutiny. Just because people accept and participate in a system, does not mean that it is just and that it is not worth changing or criticizing. Beyond market forces, we must also consider extenuating circumstances that economic data do not usually capture.
