1) Mindset and Culture. The idea of entrepreneurship, hard work and reward for risk is becoming completely alien to Germans. New technologies and high growth sectors are almost exclusively perceived in terms of their risks and downsides. Security, reliance on the government for problem solving and tall poppy syndrome are paramount.
2) Overly complex civic systems. Germans always were famous for their bureaucracy. But government interference in the most minute details of running a business, endless red tape and micro regulations have made it largely impossible to be competitive on the international stage.
3) Poor Work Ethic. What? The Germans? Aren’t they known to be the hard working ones? Well - somehow, our trains are also known to be the punctual ones. These cliches might have been true during the “Wirtschaftswunder” - but today, Germans work the fewest hours of any OECD country.
4) Climate Focus. Germany’s government is focused on a largely ideologically driven understanding of climate change prevention. It’s not just that Russian gas is no longer available - in addition all nuclear power plants were shut off. Climate regulation and taxation also adds to rising energy prices and production costs.
5) Worker Rights: Germany has very high levels of worker protections, making it hard to scale workforces up and down and near impossible to dismiss employees for performance reasons.
6) High Taxes. Germany has some of the highest corporation and personal income taxes in the developed world. And while e.g. Scandinavian countries have even higher taxes, in Germany it doesn’t feel like you’re getting something of equal value back from the state. This is of course highly subjective.
7) Few Future Industries. Germany’s industry has focused on gas powered mobility and advanced machine building - and has become a world leader in many of these areas. It has, however, very few software, AI, or other companies that make up the bulk of e.g. the US economic growth.
There’s probably many more - but this might paint a picture from the inside.
German's pay a lot of taxes. Living costs and rent are sky high in cities. In the past, I reduced my hours to 28 hours a week because the difference was negligible in taxes paid. I even got money from the government to pay rent because my wage was lower.
There is a real problem where between salary band's, the money after taxes does not change significantly even if you're paid more. Working half a day only is incredibly popular for these reasons (among others). It's gone so far that politicans from all sides are publicly thinking about erasing the possibility for halftime work.
