Regulation in the healthcare industry is the reason. Healthcare companies/drug manufactures have monopolies to the rights to sell certain medications. So they can set the prices. It would be illegal to import medications into countries that have licenses given out to these drug manufacturers. Joe Biden and the democratic party will regurgitate the same lines about the healthcare system in the U.S. but their solution is to generate money on the federal level and give them to companies in the private sector which only encourages them to raise their prices even more.
