I'd suggest it's much cheaper to look into how we could reduce the regulations making it so expensive, rather than throw government money at a problem of the government's creation. At the point where we are seriously talking about the entire edifice collapsing one must take seriously the question whether the costs of our regulatory regime have managed to exceed the benefits. Right now we have a terribly irrational balance between those who are hurt taking insufficiently vetted drugs vs. those who are hurt by not having drugs available for years that turn out safe. The former are visible and the latter invisible, but they are still real. A classic recipe for irrationality.
That part's pretty easy. Reduce the guarantees we require demonstrating the safety and effectiveness of new drugs.
We also took in hundreds of billions less than we would have if not for the avoidable economic implosion and earlier ill-advised tax cuts.
