"When force is the standard, the murderer wins over the pickpocket. And then that society vanishes, in a spread of ruins and slaughter.
"Do you wish to know whether that day is coming? Watch money. Money is the barometer of society's virtue. When you see that trading is done, not by consent, but by compulsion - when you see that in order to produce, you need to obtain permission from men who produce nothing - when you see that money is flowing to those who deal, not in goods, but in favors - when you see that men get richer by graft and by pull than by work, and your laws don't protect you against them, but protect them against you - when you see corruption rewarded and honesty becoming a self-sacrifice - you may know that your society is doomed.
"... Whenever destroyers appear among men, they start by destroying money, for money is men's protection and the base of a moral existence. Destroyers seize gold and leave to its owners a counterfeit pile of paper."
~ Ayn Rand, Atlas Shrugged
