Perhaps we should take a little trip to Greece, Portugal or Spain and ask conservatives there how the "let it burn" theory is working out for them. The trouble is that socialism doesn't burn like a fire, it smolders and smolders and smolders until it finally takes its final gasps. The Soviets kept their system going for four generations, and they had nowhere near the sophistication we have to artificially prop up things in the USA today.
No, if OPapaDoc-care is allowed to blossom, it will never go away. Never.
Actually it will go away, eventually; it just won't go away for us. It took 72 years or so for the Soviet Union to formally collapse - almost 4 generations - but collapse it did; in the meantime, however, the lives of those 4 generations were destroyed, and the psyches of the fifth generation (at least) were so twisted that Russia is still teetering on the edge of the thuggishness and tyranny it took to keep the Soviet Union going for as long as it did. In the meantime, when the Soviet Union collapsed, the collapse itself just did more damage to the then-living Soviet citizens, albeit damage that more of a one-time thing than a continuing degradation.
That is how Obamacare will finally burn itself out: by suddenly and unexpectedly (at least to the average American and the politicians who are then in power) collapsing under its own weight, and taking with it all of the other government welfare (aka "entitlement") programs, after having severely damaged the lives of at least one or two generations of Americans. And the consequences of that collapse, albeit also of the one-time variety - will be extremely painful to all Americans then living - except for the politicians in power at the time, most of whom will be able to protect themselves courtesy of taxpayer money - and will most likely result in a health care system that continues to be - pardon the pun - on life-support for at least a generation following the collapse of Obamacare.
Greece is, in fact, a very good illustration of what will eventually happen here.
