I have similar xp here.
Private practices are all stuffed double with patients.
I don't even count dentists as white collars or intelligentsia, they really more like mechanics or assembly line workers.
On one hand their levels of business (I reluctant to call it work ethic) is kinda impressive and worthy some applause, on the other hand they are all money grabbing Jews and the whole dentistry is just about this. Let all the teeth of everyone rot away and fix them for bank.
