300 word discussion on Ethics of Global Drug Pricing

Question: 

Should the United States consider other methods for controlling drug pricing, such as those used in some European countries? Are there other ways the United States might use market forces or incentives from government programs to control drug prices? Given that one of the most prevalent and persuasive arguments for relatively high drug prices is the high cost associated with research and development and regulatory compliance, is there a way to combat those costs?
