I favor universal health insurance, but you’re going to pay more, not less. European countries didn’t flip some magic switch where they saved a bunch of money by just “cutting out the profit.” They do it through measures like the UK NHS setting the standards of care, so in a malpractice lawsuit the entity that says what the doctor ought to have done is the same entity that bears the cost of unnecessary tests and procedures. Efficiency is also achieved by aggressively rationing providers such as MRIs, keeping health worker salaries low, etc. There is no stomach to do any of that in the U.S.
