I do recall our tour guide mentioning up to 60% in income taxes plus 25% sales tax in Denmark.
I would be willing to entertain the idea of national medicine/insurance but anything our government touches, is run so completely ineptly and inefficiently. Look at Medicare and Social Security.
If you've ever had to help your parents deal with either of these, you would see why so much of the country just doesn't trust them to be as efficient as private insurance companies. Just hearing dh talk about how terrible our county-owned wastewater treatment plant is run, it would sicken me to think the same goofballs could be in charge of our health. No wonder NJ has the highest # of residents in the country that are moving out of state. Well, maybe after covid we are #2 after NY.
