There may be a question for how to solve it, how to make other perspectives more attractive. And let's be real, who will foot the bill.

There is absolutely no doubt about the cause. It's the economy and good luck fixing that.

E.g. unemployment in "Sachsen" may be only 6.5%, but the average wage is 3000€ while the average for the republic over all is 4300€.

Here is a map about Rent, but don't let that fool you, the average price isn't actually below 5€, price in cities is 8.50€ You'll have to scroll a bit.

And average rent increase (2nd source) went from 5 to 6 and from 7 to 8. Which of course means that the absolute change was the same and the relative change was not. It doesn't matter if it's a "market correction". What people see is that their rent goes up, dis-proportionally so, while wages don't.

And of course, the meme that they can't articulate themselves is probably true. They don't see "the economy". They see the state of their cities, the living standards of their friends and family and then the government spending money on anything and everything else but them and their concerns. (climate, migrants, factories for companies in different federal states, weapons to fight foreign wars, etc.)
