Many Trump supporters have lots of problems, and those deplorables are bringing those problems to us. They’re racists. They’re misogynists. They’re islamophobic. They're xenophobes and homophobes. And some, I assume, are good people.
one advantages the left has is that "conservative" justices tend to be loathe to overturn existing-even if clearly unconstitutional-precedent
In fact, more people having access to healthcare does cost less. That happens because it is far, far, far cheaper to treat things up front before they become catastrophic. We were not just letting those people with health problems die before. What we were doing is denying them care until they were on death's door, then dumping insane amounts of money trying to fix problems, many of which could have been fixed for 1% of less of the cost if they'd been to a doctor 2 years earlier.
And we have tons of rationing now and we had more of it pre-ACA. We rationed by what kind of job you had, how much it paid, and whether your employer provided healthcare benefits. Medical care is limited, and VERY expensive, so the only question is HOW we are going to ration it and by how much.
We have waiting lists and rationing. If you're poor, you don't GET ON any waiting list.
It is cheaper. We spend 16-17% of GDP government and private expenditures. The world average is about 8-9%, and the next most expensive is roughly 12-13. And our governments (state and Fed) spend more than many industrialized countries with universal care. Only difference is individuals in the U.S. spend FAR more, on top of already large government expenditures.
And the results are outstanding. Better on many measures, worse on others. Generally we're terrible at chronic illness that afflict by far the most people, but we do better on acute illnesses like some cancers and the very highest end treatments. It's a trade off like the rest of life.
