If you can't buy now, with "significant disposable income", will you be able to buy later? That is, if you care for home ownership at all.
FAANG/SV engineers could buy a home pretty much in any major city after some years in the industry. I have heard that is not the case in Munich, Frankfurt, Zurich, etc...
But, as said by others, comparing raw numbers is pointless. Even if we spent the 2/3k that are left each month, we'd still have health insurance and pension paid for by our taxes. We aren't forced to build so much wealth to weather bad times because proper insurance is built in the system.
What domain are you in if you don't mind me asking?
So there is much more focus on soft skills, such as leaving a good impression, properly selling your work so that the client is happy, securing future collaborations with them, and so on. And, on the flip side, hard technical skills are not that important: as long as you can produce something that works in a reasonable time and sell it well you will be fine.
