Do you not believe working in retail or restaurants are real jobs? Because the vast majority of them are not paid a living wage in the US and have to rely on having multiple jobs or welfare. Walmart even teaches you how to sign up for welfare as an employee
Those are real jobs and should be paid a living wage or eliminated if that's entirely unfeasible. There can be arguments at the edges but I think people generally agree on that.
And even if you don't, certainly an "industry" where 99% of the people "employed" don't even make the poverty line or make back their expenses (patreon and only fans would fall here) wouldn't. (The people trying to 'make it big' are probably moonlighting as retail/restuarant anyway, just as all those who tried to make it in Hollywood did in years past).
There's certainly major abuses but the 1099 and "self employed" world is even more full of them than the W4 world.
