In this instance, the two proposed solutions are: make healthcare the government's responsibility like many countries that don't have this problem, or do nothing because that solution isn't perfect.
When Obamacare was passed, 70% of the population wanted Medicare for all instead:

In 2020, 54% supported single payer health care:

I can't find any post-covid polls, but states are currently trying to step in and implement it locally. Don't hold your breath.
Edit: the medicare for all poll was under trump
As I mention in my other comment, I speculate the possibility that people think "Single payer" and "Medicare For All" are different things [1] and so report a different opinion on each, similar to how the ACA was viewed MUCH more favorably than ObamaCare despite one being the nickname for the other.

[1] ACKSHUALLY, single-payer doesn't HAVE to be simply expanding Medicare to everyone. It could be done in some other way, but the core idea of the government paying for everyone's healthcare is still the same.
Medicare is generally understood to work with supplemental insurance. Single Payer is often marketed as a prohibiting supplemental insurance.
The whole topic is disgusting, particularly the rejection of opt-in Medicare at cost by both sides.
This rejection is hypocritical to everything either party claims to stand for.
