You mean because a large chunk for R&D in medicine is done in the USA? Maybe that is because in the USA pharma companies can go mental about pricing their products, who wouldn't want such a lucrative market that's easy to exploit thanks to a well-oiled lobby machinery? I highly doubt that pharma companies would stop their R&D if the USA was to introduce universal healthcare for everyone of its citizens.
