I guess we agree on more than I thought we did.
This is why I insist on working as a contractor and not as an employee: I want to own my intellectual property until I choose to sell it, and I want to create and sell a product that's useful, not be paid for my time.
You've figured out something very important, which is that as an employee, you never get to see most (ie. all, beyond the limit of your wage) of the value you create.
I do not own any private property.
>Or was it more about you wanting to be entitled to product of your fellow man's labor?
No; in fact, the exact opposite. It is about the worker owning the product of his own labour, rather than having it appropriated when production has finished. To each according to his labour.
