I saw this when travelling in the US for work. (I am Canadian). Striking up conversations in restaurants I met staff that worked while sick because they couldn't afford to take sick days, or worked with chronic conditions because they couldn't afford a visit to a doctor.
Even worse are the major chronic diseases from our lifestyle (hypertension, diabetes, etc). These are largely preventable or manageable with early care. But, if folks don't see their doctor then the severity of the disease grows until treatment becomes something major like surgery or an ER trip (both much more expensive than preventive care).
In short. Yes, the US healthcare system is broken. Interestingly one political party's solution is to blame a past president and continue to undermine what you have, while the other party is content with the existing for profit model.
