The $240k is not for the USA as a whole, it's at best for very narrow geographical areas in Silicon valley and a handful of FAANGs. The vast majority of senior software engineers in the USA as a whole don't earn anywhere near that. If you look at say here in the UK salaries in software overall are lower than in the USA sure, but a senior dev in the finance industry in London can be very competitively compensated. Industrial sector and location make a huge difference. Finally, this all has very little to do with the E.U. or even with overall GDP growth between here and the USA. There are deep historical reasons why the tech sector particularly is concentrated in the USA. For comparison consider the prominence of the finance industry in London compared to the wider Europe, or why the car industry is concentrated in Germany. There are deep historical reasons for those too, you won't find the answers in broad economic policy in the last few decades.
