I knew a guy that had 2 of the best high paying jobs. At the same time. In sales and in the medical field.
He was a medical equipment salesman. One imaging machine or a few lab equipment pieces and he made more in one day than most people do in a month.
Mighty good money to be made selling high tech medical stuff.
Thats because selling medical or lab equipment is like selling Popcorn and soda at a sports event. Markup is about 800%
Having worked in a hospital, if you buy one of those BIG pieces of equipment every three or four years you are doing well.
Some of those MRIs or DaVinci machines cost in the millions of dollars. They are not bought without a real deep analysis. One sale will take 18 months from start to finish.
THEN, he makes the big bucks, that day.
