If you let the government "negotiate" prices, that is not a free-market solution. Furthermore, Medicaid/Medicare is itself not a free-market solution and most Americans do not qualify for it. In fact, hospitals are running huge losses on these programs and they have to cross-subsidize it by charging other patients more.

As for banning imported drugs, this is a bipartisan issue, both parties have called for allowing it, but both parties are effectively against it.
