Although I don’t agree with “The salaries are higher than supply and demand in equilibrium would dictate,” I believe that your point is overall true. One truly cannot assess whether the price is too high or too low in isolation from the law of supply and demand. The role of the buyer (of any good, including labor) is to purchase as cheaply as possible, and the role of the seller is to sell as high as possible. I’m somewhat saddened that now this negotiation has turned kinda toxic. Companies attempt to play the victim card, claiming “no one wants to work,” while labor responds with mere satire, without directly addressing the problem.
Not all rich people are smart, and not all smart people are rich. Seems kind of obvious to me now, but it took me a long time to comprehend this.
