How can choosing uber rationally as a driver, and be taken advantage of by uber both be true at the same time? Someone might rationally decide to drive for Uber, not because that is their best option, but because that could be their least worst option, among a list of shitty options. If Uber and Instacart are my only options, and I decide to go with Uber, I am still making a rational choice. But only because I think Instacart is worse than Uber. That doesn't mean these companies aren't taking advantage of me, it just means one is less shitty than the other.
