How nice for you. Finnish incomes are also thousands of dollars less per year compared to Americans, and that already takes into account the money you "save" on medical care; sounds like you're getting a bad deal.
Depends on how you look at it. While the average household income in the US is significantly higher, it is top-biased. The average income for the bottom 20% is higher in Finland at $13253/year vs $11194/year in the US. Suffice it to say that it is not the top 20% who need universal health care.
Furthermore, you're living in a tiny, sparsely populated monoculture at the ass end of Europe (...) Scaling that up to the whole population wouldn't reduce medical spending, it would massively increase it.
There's plenty of countries larger than Finland with effective and efficient single-payer health care.
