Ayn Rand's money speech from Atlas Shrugged - an excerpt

"Money is the barometer of a 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 being rewarded and honesty becoming a self-sacrifice--you may know that your society is doomed.  Money is so noble a medium that it does not compete with guns and it does not make terms with brutality.  It will not permit a country to survive as half-property, half-loot."
