Do really well. I really dislike how Americans love to decide how much a business owner deserves to make based on their value of what service that person provides, even though this is supposed to be a free market economy and the dude could just be amazing at marketing and sales and worked harder than others and has been rewarded.
On the other hand the dude is quite possibly a slimy business man (based on his history of poaching I'm judging him as shady) and should be investigated, but I hate how Americans love to hate on success because they don't know how to replicate it and think that the person must be breaking the rules. I know of so many random small business owners with no relevant education that make a lot more than the average dentist and that's what makes america great (I just heard about a 35 year old that owns 12 jimmy johns that each make him around 350k/year).
And even though this should not matter, most dentists make around $150k/year if they don't own the practice and $220/year if they do (Ada averages a few years back) a far cry from someone who should be spending $50k on something that frivolous, especially when the average grad is paying $35k -$50k a year on student loan payments(or are on govt loan repayment plans because they can't afford their loan payments), not to mention business loans or taxes which take away a huge portion of that income.
