I believe that having enough days off work every year makes a huge difference in quality of life. So much so that when our union negotiated the option to forego a 5% pay raise for 12 days more paid vacation per year, it was a no-brainer for me. If I include the optional 5 days of educational leave granted by my state[0], I have 47 vacation days per year. This is a rather privileged position of course, the average is around 28 in Germany, but I don't see myself ever going back. Last year I refused an offer for 40% more money just because it would have only offer 30 days instead.
Maybe I don't have the "drive" that is common in US tech workers, but for me this is simply a job, and more time for hobbies will always beat more money.
