I’ll get downvoted for this but so many people taking 15-50% paycuts without a moments thought, or trading 50% of pay for 3-4 hours back out of a 11-12hr workday (including commute) sort of implies that there are a lot of overpaid people right now.
A better hypothesis would be that there are diminishing returns for the hours in a day a person has. Getting back 4 hours when you are currently working 12 hours has a ton more impact than getting back 4 hours when you only work eight.
The defining metric of progress in a society is that all of us have to work less for maintaining same or higher quality of life. Leaving aside the supply demand aspects, who is going to pocket the savings if people aren't overpaid and why should they be the appropriate recipients of that savings.
Not overpaid. Even if you are paid below the market, but you are highly skilled in a job where you deliver a lot of value for the employer and you make a lot more than the average worker, you can take a pay cut. For example, average pay in US is around $50k/year. If you are very good in tech or an MD and you make $250k, are you overpaid? Probably not. If you take a $50k cut, with the remaining $200k you are still fine in many places. There is no reason to reach the conclusion you are overpaid.
The fact that you have to take a pay cut, rather than find another employer at the current level, is evidence that the original salary was well above-market
