Don't buy the propaganda. You're talking about the second-richest part of Earth, with undeniably the world's highest average quality of life. It's also a big place with massive differences.
You have to understand that when Germans are being dramatic over the economic state of their country, they are describing issues that the vast majority of countries would absolutely love to have. Economic growth of only 0.9% is very bad if you have a lot of catching up to do, but Germany doesn't, so it just amounts to being slightly behind other rich countries.
"Deteriorating Europe" is a Russo-American psyop. Luckily we have better memory - we've heard this song for at least 100 years by now, and yet here we are. That's not to say that there aren't issues, but Europeans are largely unbothered by things like the GDP growth difference between the Eurozone and the US, because it's quite clearly driven by a runaway stock market and unfathomable inequality. You can't eat GDP figures.
