Your definition of efficiency is not compatible with mine. Layoffs here are entirely based on profit increase, not efficiency. They will gladly trade inefficiency for increase in profit. They will gladly trade the sanity of those laid off, and of those who have to pick up the slack by working more and spending less time outside of work. Wealth extraction is a greedy gambit to increase profit at any cost year over year. CEOs will gladly bite the hand that feeds them, get bonuses for investor payouts, and get their golden parachute once it goes sour. They are pariahs.
