We waste more money with this "system" than most other countries spend as a total, and with worse outcomes on average [1].
Fundamentally, there are two factors, IMO, that have been conclusively proven (repeatedly, and for decades - much more strongly, recently) to be incompatible with delivering quality healthcare with some level of efficiency:
1) For-profit entities (particularly, publicly-traded / with "fiduciary responsibility" to shareholders)
2) Administrative burden / bureaucracy (partly stemming from all of the competing private entities, partly stemming from essentially impossible efforts to effectively regulate these entities and the created "market")
The manner in which the US system evolved, tying insurance to employment through basically existing tax policies, and the move by companies to take advantage of this to attract workers (IIRC), created a massive landscape of entrenched interests that works exactly like such ecosystems work. It is a "teergrube" - an absolute tarpit - where any attempt to fix problems ultimately fails.
The administrative situation is out of control, which means fraud (particularly with the turn towards "digital crime" of everyone from traditional organized crime networks to high schoolers) and waste are impossible to effectively control, adding to an already absurd situation where ever-increasing money is spent on marketing, lobbying, administrators / clerks, etc. Meanwhile, we desperately need more doctors, nurses, etc. AND, these professionals are now increasingly being politicized by "exploiters". A great many healthcare professionals are quitting, and those remaining are often trying to move away from areas that often MOST need their services!
It's amazing to watch (from the inside, so far) a country that built such "soft-power" might ... such a dominant "marketed / exported 'culture'", have those same tools (used, in any scenario, intentionally or not) turn against itself (/ be turned against it) - sowing the seeds of collapse in all sorts of systems, top-to-bottom.
There isn't a face or palm big enough for the facepalm this BS deserves.
