Its probably necessary but not sufficient for there to be more competition in this area. That there are nationwide shortages of saline bags and sodium bicarbonate indicates massive market failure, without evening considering more complex drug politics. You raise a good point about drug companies not being the sole source of predatory pricing in US healthcare. US healthcare is in the neighborhood of $3T whereas drug spending is around $300B, though drug spending is going up faster than health spending overall.
