This is quite gloomy, almost echoing the Euro opponents of the late 90s who founded the AfD. It is unclear what Germany’s actual disadvantages from its Hegemon position are. It’s neither higher interest rates nor inflation. The widespread dissatisfaction in the population has more to do with immigration than with Europe. Since more than 50% of Germany’s export go to other European countries, I would argue that there is more benefit than downside to Germany’s role within the EU.
