Nope. Not even in the EU. Not even close. Where does this myth come from? Is it that it has passed the UK per capita?
I mean, there are loads of nice things about Germany, and economic strength is one, but that's a wild exaggeration.
Per-capita in the EU is skewed by a fair number of very small but very very rich countries. Luxembourg, the leader, being a tax haven and a population of half a million (!!) does not make it the healthiest and best economy.
Germany is certainly not the richest country in Europe but it has been one of the most successful when measured vs. 15 years ago. But that was achieved mainly by keeping wages low so that Germans, while usually living comfortably and not threatened by unemployment, have much less wealth than people in the UK or US.

But it's probably mostly network effects. The US has an extremely complex tax code and SV is one of the most expensive places to live. It still remains a favourite among founders.
Germany sure is nice country to live in, but it benefits a lot at the expense of others.
