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.
The safety net argument has no legs. Australia and Canada both have social benefits that far exceed the majority of EU nations, yet pre-pandemic there was no shortage of $150k+ dev roles.
I promise you, the market for developers does not top out at anywhere near $100k.
That's closer to a starting salary (assuming a university degree).
