I am not referring to disagreements, I mean outright mistakes held by smart, intelligent people.  Let me turn over the microphone to Ariel Pakes, who may someday win a Nobel Prize:

Our calculations indicate that currently proposed U.S. policies to reduce pharmaceutical prices, though particularly beneficial for low-income and elderly populations, could dramatically reduce firms’ investment in highly welfare-improving R&D. The U.S. subsidizes the worldwide pharmaceutical market. One reason is U.S. prices are higher than elsewhere.

That is from his new NBER working paper.  That is supply-side progressivism at work, but shorn of the anti-corporate mood affiliation.

I do not believe we should cancel those who want to regulate down prices on pharmaceuticals, even though likely they will kill millions over time, at least to the extent they succeed.  (Supply is elastic!)  But if we can like them, tolerate them, indeed welcome them into the intellectual community, we should be nice to others as well.  Because the faults of the others probably are less bad than those who wish to regulate down the prices of U.S. pharmaceuticals.

Please note you can favor larger government subsidies for drug R&D, and still not want to see those prices lowered.
