Most bankers dwell in marble halls,

Which they get to dwell in because they encourage deposits and discourage withdrawals,

And particularly because they all observe one rule which woe betides the banker who fails to heed it,

Which is you must never lend any money to anybody unless they don’t need it.

Ogden Nash (1902-1971) American poet

“Bankers Are Just Like Anybody Else, Except Richer,” New Yorker (7 Dec 1935)
