Europe is the free-rider continent

I can only speak about Germany but 35 hours weeks are long gone except for some large companies, retirement age is 67 now, which is far away from one "being in their prime".
Germany's arms production is very advanced, the Leopard 2 is one of the best tanks in the world, German submarines are apparently the best non-nuclear submarines you can buy, and German guns are used all around the world. The government just somehow didn't want to put much money into defense which was luckily now reversed swiftly.
In general the EU has put great effort in projects to develop weapon systems that are used by more than one country, see projects like the Eurofighter, A400M, and NH90. It might not be enough but the article just dismisses it as if it didn't happen.
The praise of America's "cut-throat model" also ignores all downsides of it. High poverty rates, bad healthcare, and in general high inequality.
And it not just German arms, French subs were good enough for Australia, Belgian small arms are used by everyone... I could go on.
Well considering German arms are nothing more than show pieces, it's output is, well, zero. Although this could be changing as Germany finally changes its defensive posture after the Ukraine invasion.
Well, being arms exporter number 4, after the US, Russia and France, and in front of China is definitly not zero. Now exclude the really expensive stuff like the F-35 and the picture even looks less clear. Well, I dont consider arms exports to be a good thing to brag about. But every statistic I know of clearly shows the EU, and Europe are much more inovative and much less "free-riding" than that article might make you believe.
EDIT: Trick question, where do you think the main gun of the M1 Abrams was developed? Hint: Not in the US. Or its armor? Hint: It is named after a place, Chobham.
Europe's failure to spend sufficiently in its defense has absolutely nothing to do with the US dollar's role as the global reserve currency.
When it somes to hardware, again excluding consumer tech (where most tech is actually Asian), Europe and Japan seem to be, still, the front runners. Or how many micro chips would be made without German machinery? Or consumer tech without industrail robots. The US excels at marketing technology, as an over simplyfication I'll attribute that to an abundance of VC money and a hige one-language market.
More than would be made without Dutch machinery, seeing how as ASML is a Dutch company, spun off from Philips, another Dutch company.
