The US does spend the most and that leads to output, but that doesn't mean it's the most efficient or does the best job of prioritizing the populations best interests over political or business concerns.
The selection process of awards like the Nobel Prize is also at risk of bias given that many of the people involved in picking the winners are themselves part of the national laboratory machine.
Regardless, my point was simply that we probably have a better chance at a Swedish effort leading to less biased and more efficient research than one from the US right now. I wasn't aiming for a debate on the relative political roots or leanings of publicly funded research labs.
That said, nationalisation is sometimes the correct move as the opposite of privatisation which is also sometimes the correct move, so attaching labels like 'socialist' to it to tar the policy is not productive (just as tarring something as 'capitalist' also does not beget good thinking about policy).
