It's also huge in other developed EU economies - the best paying cities for tech in Europe are outside the EU (mostly London and Zurich). Dublin would probably rank, but it's mostly made up of American tech giants with less domestic activity (and Dublin's housing crisis makes London's look trivial!).

In addition to that, you need to live at least 20 minutes away from the center if you don't want to burn your entire salary on housing and food. It was always expensive to live in the center, but after the recent inflation spike it became even more insane.
