I had a somewhat similar discussion, and it turns out many people from different origins and Culture think differently. And hence why politics are complicated. In America that would be considered as hard working American. Some are proud ( until the hard cold market reality got in to their end I suppose ) and they don't even think there is anything wrong with it. In Europe, that would be considered as Market and Companies taking unfair advantage over its citizen on labours. And should be condemned as evil and greed. Then this often leads to discussion of US with little regulation, and comparatively EU with many regulations.
The hardest problem to solve are problem that many don't seen it as a problem. In the case most Uber drivers in US don't seems to be having an issues with Uber.
You can not choose to not pay tax. Well, you can choose that but you will go to jail and be potentially sodomised.
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?
Groceries don't fall from the sky. Somebody has to make them. So the option here is to either take from people to give to people who choose to irresponsibly have children, or don't.
If you chose the latter, then the optimal reproductive strategy would be to breed as much as possible and have other people take care of your children. That is not a 'globally optimal outcome'
If you jump into a river, other people should not be liable to bail you out if the water is faster than you thought (or never thought).
