"please convince me otherwise, but keep in mind I have a very strongly held opinion that I consider to be an unshakeable fact, and by the way I'm asking you for evidence while providing none of my own. But it's a fact."
Just ask your favorite AI "How U.S. compares to others countries in healthcare metrics?" and you'll probably get a detailed list of how U.S. healthcare is more expensive than many other countries while ranking quite low in outcomes: life expectancy, maternal and infant mortality, chronic disease, ... (and also having part of the population out of the insurance network)
You are entitled to have whatever opinion you want on the matter, but that doesn't change the facts.
Please educate me.
What possible reason is there to oppose universal healthcare?
Please keep in mind that factually it’s cheaper and results in better outcomes in every developed country in the world.
