This work investigates whether the separation of commercial and investment banking, mandated by the 1933 Glass-Steagall Act, remains a necessary regulatory framework for modern financial stability. George J. Benston, a noted scholar in finance and accounting, utilizes historical analysis and economic theory to evaluate the origins of the legislation. He challenges the prevailing assumptions regarding the causes of the 1929 market crash and argues that the repeal of the Act would not necessarily precipitate a return to the systemic failures of the Great Depression era.

Experts recognize this text as a significant contribution to the debate surrounding financial deregulation and the historical interpretation of the Great Depression.
