Actually, many of those countries don’t have systems similar to Medicare for All. Netherlands, supposedly second in this list, has a mostly privatized system with mandatory insurance, so does Switzerland. France and Germany have semi-public and private health insurance companies. The US has bigger (and different) problems than merely the existence of health insurance companies.
For a laugh (and cry), you can have a look at which countries are above the US in terms of life expectancy. It includes the likes of Maldives, Costa Rica, Panama and Oman.
Discard the Brownshirts, their collaborators, and the Putin fluffers, and you probably won’t have many choices left.
Where I’m from there has been a minimum income guarantee since 1965. In fact, the constitution says the government should ensure every resident has sufficient income to live. A single-person household with someone who is permanently unemployed receives about $1500 per month (you receive additional money per child). This is the lowest income a legal resident is allowed to have. Every rich European country has a similar system, though most opt to cover rent for the poorest, and give a smaller amount for the remaining expenses.
It turns out that willingness to work isn’t an issue, because most people don’t actually like to do nothing. The employment rate is far higher than in the US.
It’s pretty funny to me to see Americans claiming that a full-time job should be sufficient to have your basic needs met - as if the unemployed should live in dire poverty.
The Wlz (which replaced the AWBZ) covers only a minority of total health care costs. Expenses were €29 bln in 2023. “Mostly privatized” is accurate.
Both the Netherlands and Switzerland have universal health care systems and negligible rates of lack of insurance. My point is just that private health insurance isn’t the (only) problem, as these counterexamples show.
