I wish we could all be honest about how health care is just a hard fucking problem to tackle rather than saying that a particular system is completely broken while another system has got its shit in one sock.
Despite general displeasure with the US healthcare system, 71% of Americans are happy with the quality of their personal care.
Despite general support of the UK's NHS, only 24% of UK public are satisfied with the care provided by NHS, with 71% saying the number one dissatisfier is wait times for care.
The US healthcare system is expensive and by some measures less effective* than other country's systems, but no other country's system comes close to producing the level of consistent investment and advancement in medical innovation/technology seen in the US system.
All systems have trade-offs, and anyone telling you otherwise is only trying to win an election.
*Poor health outcomes in the US are more attributable to lifestyle choices (diet, transportation, gun culture) than the quality of care provided by the system
