imho there are multiple, starting with the pension and healthcare system which are not sustainable with the current demography trend, which pushed them into going all in with immigration, which fractured whatever was left of german identity (which was arguably already wiped out after ww2 and the cold war). Taxes are going up, retirement age is increasing, pensions are decreasing, public services are getting worse year after year, there is nothing young people can focus on, nothing they can expect to have better than their parents or grand parents, most will never own their place. The self sabotage of the energy sector certainly didn't help. No long term vision + no clear way to improvement + no sense of appartenance = game over, and this is hitting most of the west at once, it's all about individualism and consumption, you can't build societies on these principles.
> it's all about individualism and consumption, you can't build societies on these principles
Lots of real problems listed, but such a non-sequitur conclusion. US is built on these principles, China seems to be more individualistic and consumerist than Germany too. If anything, a big problem in Germany is low ambition as the societal norm. A bit of consumerism could actually help with that, as to consume you need to earn, and to earn, you need some ambition.
What is the "current demography trend", when did it become current, how does it compare to 35 years ago?
If anything, _more_ individualism and personal responsibility would help, not less.
You wrote my thoughts. Add one more thing: Germany is federation with insanely complex administration. With many different (outdated) education systems, too many public healthcare insurers. It’s too much of regulation of everything decreasing real efficiency to zero.
Latest example (I am electrical engineer AND electrician): from this year on my buddy heating system specialist can’t help me with photovoltaic system installation on the roof. Last year he was qualified, this year not anymore. He can however install air conditioning unit on the roof this year too. But not the solar panels… Every year some shady lobby group writes some special law crippling last pieces of working system.
There should be some deregulation and centralization institution in Germany with a real short time efficiency increase plan. Otherwise it will stay there as a country of Oktoberfest and Cologne Carnival.
