It's proving that the US, which spends BY FAR the most on healthcare per capita, is getting a very poor return on our investment.
It's not really "helping" because the GOP is so opposed to healthcare reform - which would cut into their corporate profits, and they've somehow persuaded their supporters that Jesus hated healthcare but loved automatic weapons.
I don't know which countries you're talking about. Sweden has a population of 10m, which would make it the 10th largest US state. Norway's 5.5m people would make it the 23rd largest.
Even if we go really small and rich, Luxembourg's population is 670k - that's more than Washington DC (not a state, I know), Vermont, and Wyoming.
The only really wealthy European country that's smaller than a US state is Iceland.
