What makes you think 150/hr is worst case scenario?
If the US copies, for example, Germany’s healthcare which is a compulsory, universal multipayer healthcare system...you will be paid about $35/hr and pay higher taxes too.
Did you know a general practitioner there sees 243 patients on average per week? If your ER shift is similar volume as a clinic and you work 5 shifts a week, that's 48.6 patients per shift. (

Guess how much they get paid? 4000 euros/month to a maximum of 7000 euros/month in 12 years of practice. You then pay 40% of tax overall on that. THat means, after TWELVE YEARS as a physician, you get a measly sum of $54,902 USD of after-tax income per YEAR. (

Did you know 40 percent of doctors in German municipal clinics work 49 to 59 hours a week? That one in five doctors had even higher weekly averages of 60 to 80 working hours, including all services and overtime? You add that up, that leaves only 40 percent of doctors working LESS than 49 hours a week. That is absolutely disgusting for how low they get paid.
So, if you do the math of 7000 euro per month divided by a 50 hr workweek you get 35 usd/hourly pay. (

Also, things are perpetually so bad that German doctors went on STRIKE back in April of this year. To demand a measly 5% pay raise, asking for caps on the number of hours they are forced to work, asking they be paid extra if forced to be on call, and asking for at least two weekends free per month!!

Yeah, THIS is a worst case scenario that actually exists in real life. Better think hard on your plan B after the 2020 election.
