> The money we (the US) do spend in education/healthcare/infrastructure is already poorly utilized, why would we want to spend more and end up like that?

The whole point of a single-payer system is that you will spend less, by virtue of the government using its single-buyer negotiating power to push down prices.

And also by virtue of firing all the useless parasites and middlemen that create, consume, and shuffle the mountains of paperwork that surround US health insurance, advertising, billing, etc. Unsurprisingly, these middle-men don't look kindly upon being eliminated, and have somehow convinced half the country that if it weren't for their heroic efforts, grandma would never get a cardiac shunt, and that the world would literally end if Medicare was actually allowed to negotiate drug prices.
