Doordash could just employ delivery drivers to solve this problem. No need for a 100% at will temp work force. They could just hire people part time or full time. And if work is really that surgy they could just have workers on call.
Why does “innovation” have to go hand in hand with fucked up labor practices?
Because we live in a capitalist society and profit is the only objective.
Not exploiting your workforce as much as you can is an almost guaranteed road to failure.
Imagine taking investor money and saying "I'll pay more to my workers so they can have decent lives". They'd oust you in a second. Same if you're in a publicly traded company.
The only possible way this doesn't happen is if you're running an already profitable private company, you're willing to grow at slower rates (which carries its own risks), your market allows it and you're not a sociopath.
