I think European dev market is a lot more complex than that; if you work in Zurich or London, do contracting, work for a major bank etc then the market is way different for you than if you do (say) PHP as an employee of a non-software company in Berlin.

The baseline is decently middle class with a solid safety net but there's a lot more room at the top than you're making out IMHO.

As always, to make cash as a "working" dev you have to get as close as you can to a gigantic money funnel of some sort. The main difference from the U.S. is that there are fewer and different money fountains, especially missing unicorn and VC money. Finance, FAANG outposts and doing specialised things for huge real-economy companies still pay well.
