My opinion only, but when we look at 'normal' pay rates for given occupations, I think the Internet gives us the expectations for an employment situation. When one runs and operates their own business(es), really anything goes. He'd not only be getting paid for his labour working the job, but also the markups and additional charges.. the 'profits' that would be collected by the employers of the employee-denturists the internet pay rates are quoting. Then..lots of write-offs, etc. And it seems he built wealth in real estate as well over a long period. jmo.
