On your 6th point: there are more than enough people in STEM. Just the biggest technical university has over 50k students. And there are plenty of other universities around. The truth is that Germany just doesn't pay enough to have these people actually stay here. That's because you have a bunch of old greedy fucks run the economy. Source: me, an engineer. It's easier to just move abroad or work remotely for a foreign company, or move even to one of the neighbouring countries, and make almost double the salary in the field. France, Denmark, the Netherlands all pay me better than Germany ever did. Germany doesn't innovate because it is owned by old greedy fucks that make it next to impossible to start a company. In the UK it costs under 100 Euros and one hour to register a company. In Germany it costs thousands and A LOT of precious time of your life. I say this as someone who TRIED to start a company in Germany :) This is cultural. Germany has an obsession with being cheap. And it shows.

Anyway, your other points are full of flaws. There are around 4 million people living off of welfare. There are almost 25 million pensioners living off of what you probably don't consider welfare, but in fact is welfare. There's your problem. Not only that, but there are less people that live off of welfare now than ten years ago. The numbers have been going down slightly over the last decades. Also take into account the fact that many of them actually work and need welfare to stay afloat.

There should be a major focus to support families, especially academic families.

How would you go by doing that? What do you propose? Funnily enough, almost all students in Germany come from families with an academic background.

The most successful people don’t reproduce, leading to a massive desrease in intelligence.

This sounds like eugenics already. I see you have a big obsession with "the educated class" here. That is.. interesting to say the least. Your so called "educated class" won't produce your goods, keep that in mind. You need everyone to have a healthy prosperous economy.

Green ideology

I see you speak from a very unbiased position here. What is this said "green ideology"?

Long story short: Germany has always been unattractive to foreigners and will stay so. The only people that ever migrated to Germany did it because they didn't have any other choices. It's the same with the turkish workers that came here half a century ago. Germany treated them like crap, refused to integrate them for many years, even sent their kids to schools to study in Turkish and didn't want them to learn German. It's the same story with arab refugees. It took years for them to get work permits here. The government paid teachers to teach in arabic and refused to teach them German because they feared they would settle here. Many of them have to fight the government to get a work permit and actually be able to contribute to society. This is what the german mentality has to offer.

Older generations aren't ready to accept people from other countries and cultures here. They want quiet, little slaves ready to work for cheap. Even better if they're highly educated. This just feeds back into the german cultural aspect of being cheap. That's why educated people like me work abroad. Germany is mediocre at best. My mates in Eastern Europe make the same as the Germans in my field in Germany. It's hilarious honestly how much they tell themselves how superior they are, but they work on EE wages. Germans expect everyone to flock to their country and learn their language, but Germans can't even order at McDonalds in English when they go abroad. They don't even bother integrating the people that come here, yet they keep saying how they want more skilled, educated immigrants lmao

Look at the people Germany is importing and the conditions they live in. Even people from Eastern Europe get treated like cattle. They get brought here by the corrupt political class to work in meat factories. They barely get any money, they are tricked into living in miserable conditions, they get to sleep in a small room with six other men that are also working in similar conditions. This is how Germany stays afloat. By taking advantage of people and being cheap. This will not work forever. Being cheap and taking advantage of people doesn't work indefinetely. I just find it hilarious how German society has to wake up to that realization now.
