Europe is not like America, average age of European parliament was 49 years when they where elected so logically 52 now (1)
Politicians seems much older in united states: "The average age of Members of the House at the beginning of the 117th Congress was 58.4 years; of Senators, 64.3 years."(2)
Age has nothing to do with it. Every generation has imbeciles. Gen Z will have lawmakers someday that believe AI can be elected as judges because they are infallible. Or something equally ridiculous.
Be careful: for every argument you make about the ignorance of older people, another argument can be made about the ignorance of younger people. Valid or not.
