We are not the only nation developing new drugs (though we do develop a disproportionate share): "Although the United States comprises only 5% of the world's population, it accounts for 36% of worldwide research and development of pharmaceutical drugs."<quoted text>
research is very expensive.
Patents protect integrity to reclaim expenditure of research. The USA pays 100% of the research cost, and subsidies the world with medicine.
Only USA customers pay back the companies that develop new medicine. All other countries medicine pricing does not include research cost.....we pay that.
Why should we subsidize drugs for the rest of the world? Why shouldn't we use our buying power to negotiate for the best prices?
