I have an older family member in England and it's a nightmare. She needs specialists, which isn't the hardest part, but it's the approvals for the medicine and therapies which are extremely difficult to get approved, so she's on bad generics and bio-similiars and first-line type medicines that don't work because it's too expensive and hard to escalate treatments.
I feel bad when our family compare notes (genetic/hereditary disease) and compare it to the care and treatment we get here for pennies on the dollar with amazing PPO/EPO type plans from Fortune500's.

But yes, it's generally understood by everyone that the basic rudimentary care of ear infections and flu and cold and preventative care and easy peasy stuff, the socialized system is best. But when you get to three or four levels into chronic and expensive illness and diseases, those systems generally breakdown and suck and "enshittify" due to having to limitations in money and using statistics of large numbers.
