Everyone's not walking around worrying about the gig-worker or the driver or the janitor, beyond the fact that that they get food on time, reach where they want to be, and walk on clean ground.
I even presented the solutions to these. Don't fake pity me - that's easy internet keyboard warrior thing. Do the work of changing the system you're part of.
It is only part of the world (or even the US) that behaves like this. And there's nothing given that says that the parts that do must. We can as a society choose differently.
And the problem with your solutions (not that they are bad in themselves), is that they will never gain traction while people believe that the economy is the end and not a means. It is easy to argue against socialism, et c., if you think that the economy is the only thing that matters. But it is hard to argue for the current system if you believe that what matters is people in themselves, not the role they play in the current capitalistic system.
