So the situation with the US is that, their spendings on healthcare is gigantic percentage of their GDP and Germany is a distant second with the rest of the Europe and the world trailing behind. US also doesn't have much to show for that spending, all the health and longevity metrics are worse than Europe. The defence is usually that Americans are paying for R&D and UK, Europe and the 3rd world are freeloaders. The counterargument is that, US relies heavily on immigrant researches that were trained in those countries those they foot some of the bill for the R&D and non-trivial costs of the healthcare in US is in administrative costs and not drug or machinery that was R&D'ed in US.
So we can argue over the issue all they long but the fact remains that there's lots of accounting differences so it's not possible to compare GDP number to GDP number and if you compare other metrics about the output of that GDP, the USA lags quite a bit behind countries with much lower GDP or GDP per capita.
US of course has it's own unique strengths, making it the dominant country of the world.
It changes substantially, when PPP is used China surpasses the US with a significant margin.
For example, having an appendicitis in US increases the GDP by $10K but in most of Europe it barely moves the needle, thus Europeans lag in GDP metrics for the same healthcare.
Fresh, healthy produce as standart? Maybe good for people but destroys the GDP statistics. If Europeans embraced the idea that healthy stuff is for the rich and charge for it accordingly, they too can extract much more numbers from the tomatoes and have nicer GDP.
