The primary "engineering" of the American medical system, is social and financial engineering. Of course they can sometimes produce useful medicines and procedures ... for a price. A price ... is inevitable (no, not communism ... Joe) ... the primary disconnect in America isn't the price ... it is the blind faith that medicines and procedures don't have unfortunately consequences, that have to be judiciously considered ... and that everyone is entitled to expensive medical care. I certainly wouldn't deny anyone an aspirin (if they aren't allergic to it) ... but the idea of a bottomless sugar daddy, paid for by exporting inflation to Third World countries ... is that ethical?
I guess we can export inflation. I heard we export environmental degradation, but that was by a timber industry representative who was trying to heap a guilt trip on environmentalists that were trying to slow down deforestation (in the US) causing us to import wood products from Canada, and thereby passing deforestation onto Canadians, but my eyes soon glazed over, because while the economics and the trades were probably true, it's motive was to make a case for fucking up our own environment rather than the rain forests of South America, or the taiga of the Canadian wilderness. The argument was completely missing the whole point of deforestation, either locally or globally by looking at the problem through a tiny hole. But I digress.
Medicine is expensive, but more so than it needs to be. Remember the Obamacare death squads that would keep costs down by NOT allowing people to have access to the system? Well, it was probably true, actually is true, but instead of the death squads being administered by the government, it's being done (as it always has) by insurance corporations, which have every incentive to be even more heavy handed. But I'm still digressing.
Medical science has the same problems as science. It sometimes gets it wrong and it's continually being refined or corrected, but that hardly makes a case for switching our health care over to shamans and medicine show snake oil salesmen.
The reason this post may not be all that coherent and easy to follow is because I'm responding to a post who's point I didn't understand either. Annoying isn't it?
