As a disabled person who has also benefitted immensely from Uber, I hear this a lot, and it is really frustrating.
No one will help me, especially progressive leaning people. You don't get political or social brownie points for helping disabled people the way you would for other minority groups who are struggling. We are constantly ignored and forgotten.
I was in a situation where I needed money for healthcare that will never be covered by insurance, especially government sponsored universal insurance (EDIT: it will be covered eventually, maybe in 10 years). Gig jobs played a key role in my ability to purchase that healthcare and survive.
Regular employers will never hire me. Unions will never let me join them, because I can't meet their requirements and make life harder for their able bodied employees. Gig work is the only option.
Healthy people aren't nearly as caring as they'd like to believe, especially progressives.
