Germany also has been facing two big challenges that have seen limited action: rising energy costs and slowing exports to China, both of which have started around 2020. The decision to rely heavily on Russian energy to sustain its industrial economy has proven to be a bad idea. The influx of low- or unskilled labor into a social welfare system, coupled with the challenges of cultural integration (German culture isn't the sexiest of things), has also turned out to be a bad idea.
Bonus issue: Germany’s taxes are high, particularly for individuals and workers. Some of the highest in the world. This gives consumers less $ to consume with.
