As far as Obamacare, you should watch a few videos of Jonathan Gruber, a prime architech that met with the White House Staff over 20 times and with Obama at least once. Obamacarewas never meant to "control cost". It was never meant to provide gtreatment. It was meant to redistribute income and really never was intended to be successful. Regardless of its success or failure, it was simply a step to a Single Employer system that denied treatment to the masses and provided treatment to the privileged.
Once again, the costy of healthcare in the US had been a relatively stable 7% of GDP before 1965 at which time it began to rise sharply and has continued to do so. That was the creation of Medicare and Medicaid. One has to be nuts to believe that the government will come up with as solution to solve a problem that it has cereated.
