Over at Money Law, Marie Reilly has an interesting post on the movie "It's A Wonderful Life" (click on link to view) and the history of the financial services industry. An excerpt:

  At the beginning of the 19th century, there was no banking as we know it. Rich people needed safekeeping services to store gold or other forms of wealth, and banks provided secure vaults. The first depositary savings bank is thought to be the Philadelphia Savings Fund Society, established in December of 1816. It launched an industry that profoundly changed the American economy.
  Savings and loans emerged as small businesses that accepted cash deposits from customers and made loans to borrowers in the community. During the nineteenth century, as urbanization and wage income grew, savings and loans encouraged wage earners to save. They replaced extended family as a source of capital. And all in the nick of time to finance the rapidly growing consumer sector. A wage earner needed finance to acquire the "American Dream" consisting of big ticket items like a home and a car. The connection between savings and loans and the emerging consumer middle class was more than skin deep. As a regulatory matter, savings and loans were "of the people" in a way that banks were not. Depositors controlled the investment strategy deployed by savings and loan management. In contrast, equity investors, usually with no connection to the deposit community (e.g., Mr. Potter), controlled the management of banks.
