I believe that there is an important kernel of truth in the idea that financial errors recur every other generation.
James GrantThe art of banking is always to balance the risk of a run with the reward of a profit. The tantalizing factor in the equation is that riskier borrowers pay higher interest rates. Ultimate safety - a strongbox full of currency - would avail the banker nothing. Maximum risk - a portfolio of loans to prospective bankrupts at usurious interest rates - would invite disaster. A good banker safely and profitably treads the middle ground.
