Waste of time you say? Were never life changing?
I'm curious to hear what's your definition of "life changing"?
Salaried tech compensation in Europe grew quite a lot over the last 10+ years. Still behind US, but no longer by as much as before.
Back in 2005, 2010, and even 2015 - companies were benchmarking salaries locally (and even down to that specific country). With FAANG opening up shops in EU, all other bigger tech companies started to benchmark compensation somewhat globally.
I know plenty of European software engineers that got a house with 30 years mortgage, and (with salary, RSUs and bonuses) paid it off in <10 years.
Granted, cost of real estate is now 3x compared to 10-15 years ago (other costs are also bigger, but not 3x). From what I've seen it's the same just about anywhere in Europe.
So if you just got a mortgage now, it will take longer.
But still - there's usually enough salary left (even after spending on traveling with 25+ vacation days) to put loads of money into rainy day funds, expensive hobbies, as well as investments/FIRE.
Most other sectors are not really close.
