Every single thing is so obsolete. Nothing is digitized. Everything requires a giant stack of actual paperwork to be taken to an office where the whims of the clerk dictate everything. A million rules exist in the hopes that they cover all possible scenarios, but inevitable they don't and if you happen to have a scenario which is not covered, you're shit out of luck because the clerk is sure as shit not going to put their ass on the line and make a decision not explicitly present in the rule book.
You pay through the nose for health insurance, but when you need to find a doctor, none can take you because their quota of public insurance patients is done for the quarter. If I paid the same amount in insurance in India, I'd have a helicopter flown out every time I stubbed my toe.
And then there's the wait time for everything. Appointment for visa extension: 8 months. Driving license conversion: 1 year. German exam: 5 months. What, you want the results for your exam also? Better wait another year then. Honestly Germany is a shit show, and if I hadn't already invested so much time, money and energy into this god forsaken country, I'd be out of here in a heartbeat.
But the worst part of all this is - the vast majority of Germans think this is all acceptable and okay. If you go to the /r/germany or /r/de subreddits, any thread with genuine complaints will be drowned in responses from native Germans who naively believe that Germany is a great country to live in because they either don't have these problems, or they know how to work the system and get their results. So there is no voting pressure to get things to change. So long as the omas and opas get their pension, Germany will stay as it is for ever - there is no need to change in their view.
