"The sense of responsibility in the financial community for the community as a whole is not small. It is nearly nil. Perhaps this is inherent. In a community where the primary concern is making money, one of the necessary rules is to live and let live. To speak out against madness may be to ruin those who have succumbed to it. So the wise in Wall Street are nearly always silent. The foolish thus have the field to themselves. None rebukes them."
John Kenneth Galbraith, The Great Crash of 1929
“A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. For the traitor appears not a traitor; he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear. The traitor is the plague.” Marcus Tullius Cicero
