Many countries, such as the UK, have universal healthcare which is free and widely available to residents of that country. While there have been previous questions on why state-run and national universal healthcare systems don't exist in the US, I am curious if there are any active existing examples of universal healthcare, paid by local US government, through taxes, whether that is county, city or in a town?
This is a partial answer. Vermont had plans for a single-payer health care system, but in the 2014 the plan failed because the state could not find the budget to cover the expenses (quantified in 2 bilions $, for a budget that normally is of ~8 bilions $).
Side commment: Funnily enough, the average health insurance cost in the Vermont state is 468$ per month per person. Vermont has ~600'000 inhabitants, of whom only 3% is not insured. since 300'000 people are privately insured, with the rest being covered by alternative programs (medicare, meidcaid, etc) ... the planned budget would have made cheaper health insurance for Vermont inhabitants on the whole.
