Medical field here: The vast majority of us are not in it for the money. Physicians have to spend 3 to 9 years after medical school working for a wage that works out to about $5/hour to gain certification and a medical license in their specialty. And that’s after 8 to 12 years of undergraduate/graduate/doctorate education that basically has to be paid for with loans unless they’re in the military or come from a rich family. So, yes, physicians do make high salaries once they’re established, but there was a lot of work and sacrifice to get to that point, and very few people are masochistic enough to put themselves through that just for the money.
Also, the most expensive parts of a medical appointment/surgery/ER visit etc is the administrative overhead, inflated prices of drugs and supplies, and insurance company bullshit. Very little money from that price tag actually makes it to the healthcare workers. Your average EMT on an ambulance makes between $13-20/hour depending on the state minimum wage.
If you have a problem with your healthcare costs, that’s something to take up with your representatives in government, not the EMTs, CNAs, nurses, and physicians providing your care.
