Ludwig Von Mises (1881-1973) Austrian economist.
We do not live in a society in which a wealthy lord pays a worker whatever he sees fit, and the worker must submit in order to survive. We live in a market economy; an economy in which if you offer something that people really want, an employer MUST pay you a higher price, or else his competitors will obtain your services and pay you even more (so that they can add that value to their own company). If the first company regularly undercompensates those with valuable capabilities and loses them, it cannot compete effectively and ceases to exist. Like oil, gold, or anything else, when it comes to ability, value is related to rarity. The more desirable and rare your contribution is, the more it will be coveted. It is your fellow man, the customer who determines the value of what you offer.
