If we can focus for a moment on a substantive issue in the midst of this presidential campaign, we all know that one of the top priorities for a new Republican president has to be the repeal of ObamaCare. But it is neither possible nor desirable to go back to what we had before ObamaCare, which was hardly a market-based, patient-focused system. It basically used the tax code to manipulate people into being dependent on employer-provided health insurance for even the simplest of health needs. What ObamaCare did was double down on the problems inherent in that system so as to make it even worse.
