So? Social constructs have a lot of teeth in the real world, and always have. Wishing them away won't have any effect.
> I'm saying there should be no special benefits for employees
So are you arguing that those benefits (i.e. health insurance) should be universal? Or are you making the argument that only those in a position to pay should have access to those things?
Laws and social constructs can be changed.
As for health insurance (as an example), how do you justify giving health insurance to employees, but not to other people, like self-employed people?
However, to address your question more directly, contractors are employees as well. It's not the job site's responsibility to provide health insurance, it's their employers. Contractors still have employers, you know.
This is true for vendors, but direct 1099 contractors are self employed.
In your terms then, just let everybody be self-employed and contract them, rather than employ them. That's the same result I want, that people are responsible for themselves and making a contract with somebody to do some work for you doesn't come with any additional baggage. Just plain money for work.
