Germany's GDP is estimated at $4.4 trillion for 2023.
In 2008, the high before the crash, it was $3.7 trillion. Inflation adjusted that should be $5.4 trillion just to be even with 2008. They have never recovered.
During the good years of the 1990s for the global economy, 1995 was the peak for Germany, and that high was $2.6 trillion. That is $5.3 trillion today. You can pick most years from the 1990s though and it's a bad outcome inflation adjusted to today.
28 years later and the economy needs to increase by 20% just to catch up to where they were in the mid 1990s.
The reason Germany has passed Japan is because they have been suffering from an even worse economic stagnation the past two decades.
How long can Germany pretend things are fine?
