Leo Tolstoy said this quote

“ In my considered opinion, salary is payment for goods delivered and it must conform to the law of supply and demand. If, therefore, the fixed salary is a violation of this law - as, for instance, when I see two engineers leaving college together and both equally well trained and efficient, and one getting forty thousand while the other only earns two thousand , or when lawyers and hussars, possessing no special qualifications, are appointed directors of banks with huge salaries - I can only conclude that their salaries are not fixed according to the law of supply and demand but simply by personal influence. And this is an abuse important in itself and having a deleterious effect on government service. ”
