Great point. But, alas, the altruism has long since left the medical profession.
Look at the trends, and the statistics. Medicare patients are less and less welcome in the physicians office. I stopped treating them the last 5 yrs I was in practice and quite honestly did not miss the headache. Medicade was even worse. They routinely requested a medical writeup, probably took an hour of my time once my staff found the chart, archived, or no. For that hour of time which would not and could not be delegated ($10,000 fine) I recieved a whopping $12! A week of 15 of those and I lost money. Would you go to 12 years of school to lose money?
Sorry to say it, but even med school students know where the bread is buttered.
