I meant along the lines of: I can't see how allowing medicare to negotiate drug prices, letting nurses do more of what doctors do and publishing prices gets the US medical system anywhere close to a 50% reduction in per capita spend, or gets the US any closer to covering 100% of the population. The US should do each of these. Each would make a difference.
What the country needs, though, is real reform.
And also, yes, socialized medicine is dramatically more efficient. Medicare's overhead is only 2% whereas that of private insurance is 18%. Just knocking that off the top would bring the US per capita expenditure much more in line with the OECD.
