The poor and middle class neeed large tax increases and the wealthy need to have their taxes lowered

Good news, that’s what Trump is already doing.

Our outcomes are not always worse. It’s a mixed bag.

The only–ONLY–medical metric that we lead the world on is per capita spending on healthcare. In 2022, we spent an average of $15,222 per person in the US. The next worst country–Switzerland–spent about $8000 per capita. When you compare outcomes, Switzerland gets very nearly identical outcomes to the US, but spends far less per person. And Switzerland does NOT have single-payer healthcare. Canada spends $6000 per capita on healthcare coverage, and leads the US in most outcomes.

would require much larger taxes on the middle and low class

Yes, more in taxes, less (none) in paying premiums, co-pays, or deductibles. So as far as income in your pocket goes, and in terms of medical outcomes, you come out ahead in a single-payer system. Think about it for a second; what’s your annual deductible? The insurance I can get through my workplace has an annual deductible of $7000 per person. That means that, aside from visiting my GP, I need to spend $7000 before insurance covers anything at all. That’s on top of the $6500 I would have to pay in premiums. After I hit my deductible, insurance covers 80% of my costs, until I’ve paid a total of $11,000 out of pocket, then it covers everything. So I would have to pay at least $17,500 in a calendar year before insurance picked up everything. If I don’t have insurance because I can’t afford $250 every two weeks? Then I get the whole hospital bill for everything, which, in most cases, means people declaring bankruptcy. What I’m saying is that you can take that –OR– you can take $50 out of everyone’s paycheck (scaled to income level probably, and based on a risk pool of 330M people) and just be covered, period, no copays, no deductible, no worries that you’re gonna be bankrupted by a hit-and-run driver that sends you to the ER.
