Maybe if we didn't have enormously expensive healthcare that is tried to our employers the payouts would need to be so huge. If I'm injured by medical malpractice and can't work I'm going to need a lot of money to make me whole in the US, even more so if I need additional medical treatment.
The money that goes to the injured is dramatically smaller than the money that everyone in the system pays to cover the insurance liability calculated insurance rates when the payouts can be arbitrarily set by juries. So if one jury says 600 million for one egregious case, all insurance for all doctors and all care for all patients skyrockets to trillions based on the risk assessment of insurers at that point. It is better to manage the risk with better measures (some states have a damage pool)
