> But if you have want some metric of "fairness", then looking at free time is better than looking at hours worked - because that way you measure sacrifice, and a relation between sacrifice and compensation is seen by many as fair. A better metric of fairness would be, how equal were the opportunities to become profession X? If being a banker is so great, and being a teacher is so (comparatively) awful, then wouldn't it be fairer to simply equalize the opportunities, and let a glut of bankers and a shortage of teachers balance out the wage difference?
