On the contrary, if the healthcare system in the US weren't such shit, more people would probably be going to primary care doctors and getting Preventative Care before it becomes an emergency, and requires a trip to the hospital. But many people don't, because visiting a primary care / walk-in clinic / urgent care is expensive, so they ignore it, until it becomes un-ignorable. Now it's an ER visit.
