The us health INSURANCE system is not hugely profitable. as care costs go up, the insurance deductible/premium must also go up or the amount of services covered needs to decrease.
The way to fix this is to fix the system. Lower Doctor pay, lower drug cost, showing pricing up front, allowing medical suicide, removal of middle-parties, ..etc all would allow the Us to get more care for money they spend.
Also do realize the U.S. doesn’t have healthCARE but health INSURANCE. Insurance is geared towards covering unexpected large cost events. Americans use their health insurance as health care.
