> the maximum extraction ownership can get

And people demand the maximum pay they can get. It's the Law of Supply and Demand.

Consider this. You hire Bob for $10/hr, and he produces $100/hr in value. What's going to happen? Your competitor hires him away from for $20/hr. Then another competitor hires Bob away for $30/hr. This proceeds until Bob gets paid about $85/hr. The ROI of hiring Bob is somewhere around 15%.

There's a good reason why the vast bulk of the American workforce is paid much more than minimum wage.
