Ayn Rand -

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.

Leon Uris "The Haj" -

 This is the way it is with Arabs,” Ibrahim said.

“First comes my brother and I against our father; then my father and I and my brother against our cousins; then our cousins and we against the stranger.

That is the way it has always been with us. Me against my brother; my brother and me against our father; my family against my cousins and the clan; the clan against the tribe; and the tribe against the world. And all of us against the infidel.”
