The real answer to the proposal should be:
WHY?
So the game reflects the real world where a Butcher gets payed the same as a Brain Surgeon,
who is payed the same as a Police Officer,
who is payed the same as a Baker,
who is payed the same as a Politician,
who is payed the same as a Plumber,
who is payed the same as a Candlestick Maker.....I could go on.
Because we all know every profession has exactly the same inherent value.
