Weird take. Norway has about the same gdp per capita as the USA with stricter regulations than France. Ireland’s GDP per capita is higher than that of the USA, with less bureaucracy than France but more than the US. Not to mention that all of these are before adjusting for PPP. Almost as if GDP per capita is not a good measurement of productivity.
Many wrinkles here.
First, one should probably look at GNP (or even GNI) rather than GDP to reduce the distortionary impact of foreign direct investment, company headquarters for tax reasons, etc.
Next, need to distinguish between market rate and PPP, as you highlight.
Lastly, these are all measures of output (per capita), while productivity is output per input, in this context output per hour worked. There the differences are less pronounced.
Monaco is the most productive country in the world in nominal GDP per capita. A very industrious place, it seems!
