I think it’s funny that the capitalization of nouns in German is allegedly for readability, but at the same time we can cram the new testament into four words.
Keep in mind that the memes you see are extreme examples. The vast majority of compound words consists of 2 or 3 words. Like Ofenreiniger (oven cleaner) or Werkzeugkoffer (tool box). Werkzeug being a compound word itself, made from “Werk” & “Zeug” meaning craft or work & gadget. These extremely long words tend to describe very specific, often niche items and are just rarely used in common language. Most people would call the thing in the picture more generalised “Feuerwehrauto”. Sufficient to describe it for most people, but not as precise as the long compound. It is basically a question how much details you want or need to communicate.
Weeell I mean we use abbreviation for the really bad ones. BAföG being my usual example. And I work with international students so with some I see how they learn German from the beginning. My favourite moments are when they discover words like Arbeitsunfähigkeitsbesscheinigung (wich we abbreviate with AU or just Krankenschein), Geschwindigkeitsbegrenzung (or just Tempolimit) or the aforementioned Berufsausbildungsförderungsgeld (or just BAföG). I feel like there are quite a few really long words in everyday life. You just have to look out for them.
