You decided to work for a company you set up that doesn't give you any employment rights. You think that means that you shouldn't contribute the same as other workers.
Where I disagree is with "without the individual being an employee of the other". We both know that most of the time that's exactly what you are, you'd just like to arrange it legally so you can make shit loads of money.
I can see there is an issue there. I don't think it's important. At all.
