"Finally the question that drug companies are most
loath to answer: Even taking into consideration the
high costs of R&D, are the drug companies in fact
grossly overcharging the U.S. consumer? Pharmaceutical
companies are wildly profitable. Their after-tax profits
on sales are three times the average for American industry.
And the taxpayer already subsidizes the drug industry in
numerous ways, through special tax breaks and government-funded
research in biomedical science."
