That is why I have to be employed. I guarantee that after 22 years, office expenditures (rent, salaries, supplies, health insurance) would eat up the remaining $300. So taking care of Medicare patients would be charity. Medicare is 60% of my practice. Private insurance is 25%. Medicaid is 10% and unfunded is 5%.
I've been playing with the idea for a while that any time a company uses its name, it has to disclose its ownership (first the company at the top of the chain, then the ownership structure of that company). So like for example the company name "Gerber" would have to always be coupled with "owned by Nestle, a publicly traded company.", and "Dave Franklin, a Dentist in your Community You can Trust" would have to be coupled with "Owned by Private Equity Incorporated, mostly owned by pension funds".
This would make it easier to keep track of if the same company is just screwing you over and over again with different faces, while still allowing some value to remain to brands that are consistently good for customers.
