Banking became boring, partly because bankers were so conservative about lending: Household debt, which had fallen sharply as a percentage of G.D.P. during the Depression and World War II, stayed far below pre-1930s levels.
"Strange to say, this era of boring banking was also an era of spectacular economic progress for most Americans."
