You asked about not paying workers for any other career. They work once, they get paid once. That's the nature of labor. If you're now asking about onerous agreements within some purposefully convoluted industry then you are remolding the question into a wholly different scope and at that point we have moved on. Having moved on, we can consider the question about paying workers closed. It's been a pleasure.
