Yes, inflation was pretty high in 22 and 23, that hurt a lot of people.

But his claim of a "desolate feeling on the streets" being an indication of "economic conditions ... could be described as depression" read like badly written propaganda. There's nothing to be checked there, just some vague feelings. Berlin isn't as crowded as he expected, so the only explanation is that nobody can afford a car and half the population is sitting at home wallowing in misery due to economic depression? Really?
