The good folks at the New York Times have noted that healthcare costs in the US started rising sharply relative to other developed nations around 1980.
Ignoring the obvious error (Dean Baker notes that the increase in US medical inflation started in the 1970s, not the 1980s) the history is clear: this began with a major push toward deregulation that began under the Carter administration, along with largely successful efforts to privatize what had been publicly owned research and development.
The walk-back from meaningful antitrust enforcement, and to deregulate many aspects of the market economy, along with efforts to privatize federally funded research progressed rapidly during the late 1970s, culminating with the disastrous Bayh-Dole act, which had the effect of handing government research to private entities.
Later, under the Reagan administration, the break-neck pace of these changes further accelerated.
It became the wild west, and a very opaque one at that, and to paraphrase former banking regulator Bill Black, if looting is possible, it has already happened.
What’s more the proceeds of the looting are almost immediately reinvested in rent seeking activities like campaign donations, to embrace and extend the regime.
Rinse, lather, repeat.
