There is massive variation in what doctors make according to their seniority and work activity.
Independent of their hospital salary though, is their private practice income..........in the UK this is what separates the goats from the sheep.
One of my Consultants ('Attendings') for example, sweats away on 12-16 hour cancer operations in the big hospital for nothing in excess of his monthly salary ( around £5000)
However, on a Saturday, he will treat about 10 - 15 private patients performing very simple, bread and butter procedures on them and clear £20 - £40 k easily for that one day.
He is not a big watch man.........I've seen him wearing a TAG and a Baume & Mercier.
However, he likes cars...........
His colection includes : Porsche Carrera 4, Aston Martin DB9 Volante and Ferrari 575 Maranello.
