Regardless of the profession, anyone who has to see a doctor once a week is a drain on everyone else’s resources. It is one thing if one has actually contracted a disease, perhaps related to being older.
But a lot of these prostitutes would be younger and the ones that are supposedly paying into the care of their elders. But of course they are not, since they are using more resources with their weekly doctor visits than the average American is.
Your perspective is more valid only if the prostitutes were not footing their own bill for the care (as they are now), and if the doctors themselves didn’t look at this sort of practice being relatively easy, lucrative, low-risk, and veeeery steady income.
More points if the docs have personality AND can keep their peckers in their trou.
