Our health system is so amazingly bad. Even if you have insurance, you roll the dice getting even basic care. Very easy to end up with hundreds or thousands of dollars in bills if your provider codes something wrong or your insurance denies payment. Much less an actual medical issue that requires repeated trips to a specialist, an expensive medication (even generic), or hospitalizations.
God forbid we touch Obamacare though.
Obamacare also mandated coverage for basic care like your annual physical and many mental health conditions.
It’s not perfect, but I guess it’s been long enough that people are forgetting how bad the situation was before.
