The main point was that we shouldn't be celebrating that a mother of 3, going to school, and working multiple part time jobs is able to supplement their income by driving for Uber but instead be asking why is their income so low in the first place that they have to spend their nights and weekends driving in order to afford groceries. This was all in that original linked tweet. I'm sure they would rather be resting, interacting with their children, or studying for school. We can take a step back and recognize that this is a globally suboptimal outcome. At some point the "freedom to earn supplemental income" promised by the gig economy becomes "an obligation to overwork oneself in order to afford groceries." How can this person "choose to not participate in Uber's system", when they've calculated that being an Uber driver is the only way for them to afford groceries for their family?
