President Trump recently signed an executive order aimed at reducing the prices Medicare pays for prescription drugs. The move has received criticism from both sides of the political aisle, with Democrats calling it a symbolic effort intended to help the president’s reelection campaign and conservatives calling it socialism.

Instead of basing Medicare prescription reimbursements off of average sales prices in the U.S. private market, as is done now, Trump’s executive order would base Medicare reimbursements on the lowest prices paid by healthcare systems in developed foreign countries.
