That apples to oranges comparison is hardly relevant in this context.

For better or worse, Europe has much less income inequality than in the US, so European dev wages are a lot closer to the median wages, than in the US where devs make several times over the national median wage.

If you remove the big tech hubs like London, Amsterdam, Berlin, etc. then median European dev wages plummet, coming to party with the rest of the white collar jobs.
