I think too its a result of 30 years where employers have had the upper hand in the job market (except perhaps 1999, 2008). Wages have stagnated during these decades, it seems finally maybe wages can catch up.
It's getting very expensive to meet the ends. Wages will have to go up. When ppl think things aren't fair, they revolt.
House prices and rent go up to soak up as much wages as possible. An increase in wages for everyone helps nobody. Bidding on houses is a zero-sum game where we all bid against each other for the amount we can each just afford in interest repayments. Rent has congruent dynamics.
Most of us here on HN are engineers and our salaries have grown much faster than inflation.
