To throw in a data point on this for reference, as an American I pay around ~$220 a month (~$2,640 per year) on health insurance through my job, this comes out of my pre-taxed income. While I won't get into specifics on the details of the terms, I am quite happy with it.
I work in Massachusetts, but I live in New Hampshire. I pay more than double this on both Social Security fees & Massachusetts income taxes, which are non-deductible since New Hampshire has no income tax and makes up for that with higher property taxes (housing is cheaper though). Filtered to just health related services I can easily identify, in total I pay for Social Security, Medicare, and indirectly Massachusett's state healthcare (which I can only gain access to under limited conditions). Of these, only the private insurance fee directly benefits me, and I have little faith social security will actually pay out when I reach the qualifying age.
In terms of investment my HSA, and 401k are a much better dollar for dollar investment for my future finances than any government service, so I find it extremely unlikely I would ever truly benefit from public healthcare.
Despite my tone here, I'm more annoyed than upset about this. Due to the overall societal benefit, I'm not entirely against public healthcare depending on the details, I'm just under no illusion that it would be to my benefit, and I'm not much of an outlier. I'm also mostly convinced the root issue here is the inflated cost of healthcare rather than just the insurance aspect, public healthcare naively implemented would likely turn into yet another government subsidy for hospitals to devour imo.
