especially right wingers (fuelled by russian money, as confirmed more and more) need a doom&gloom environment + some targets to direct the anger/fear to. there is a lot of misinformation spread around, to an extend that group-thinking has already kicked in and confirmation biases are already at play.

the mental gymnastics are sometimes just outright insane: people with quite comfortable household income situations living in peaceful suburbs feeling close to take up arms to revolt against the evil government and those criminal foreigners everywhere (so against hated laws that don't exist in reality, people they never experienced themselves in their hood, general developments that don't affect them or also are not true/framed badly).

the reality is that life in general is good in germany, much better than in many places of the world considering the complete picture, its not getting more dangerous (criminal statistics overall are mostly flat/sinking over the last decades). there are problems, sure, but nothing spectacularly new, like aging population and pension stuff.

could it be better? always, yes. but it seems that any party that slightly tries to solve on of the actual problems gets a devastating amount of public fire (shoot-the-messenger-style) thats nearly to impossible to defend against, nowadays amplified by social media bots to a large extend, which many people are not able to identify.
