> That 3% cannot be true, Germany is at least 1/3 the European economy, and you know since i live in Europe...i worry about Germany.
Your info is out of date by a decade or more, I think.

> In 2017, according to the CIA's World Factbook, the GWP was around US $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity (PPP).
https://en.wikipedia.org/wiki/Germany
> German GDP: $3,780 trillion, $4.454 trillion PPP.
So, Germany is 4% of the world GDP in nominal terms and 3.4% in PPP terms. And that was back in 2017, developing countries are growing faster, so Germany's share probably went down.
Regarding Europe:
https://en.wikipedia.org/wiki/Economy_of_the_European_Union
> EU GDP: $18.292 trillion, $18.377 trillion GDP.
So Europe is 22% of the world GDP in nominal terms and 14% in PPP terms. And it's definitely going down as a share of the world economy.
Germany also is only only about 20% of EU GDP in nominal terms and 24% in PPP terms. This part is also going down.
You're conflating the EU with Europe. Europe has quite a few economies outside the EU: UK, Russia, Switzerland, Norway, etc. Germany is probably 12-15% of the European economy, or maybe less.
