I am also hiring, in Europe with very good work/life balance but modest salaries and like the parent I'm also not that impressed with candidates, so to me the other explanation is that candidates have a wildly incorrect estimation of what is a somewhat reasonable pay in 2025.

The position with FAANG like salaries have reduced drastically. Companies paying 6 figures just to have the privilege to have an entry level developer with this then seen as magical skill of being able to type code was a dream that is over. Look at salaries of engineers in other industries, breaking 6 figures needs a lot of seniority, $150k is rarely heard of for ICs.
