@HopelessDemigod but the banking system is so different these days than in 1929.

People don't really keep cash anymore, with banking reforms and the rise of the Federal Reserve.

Plus, streamlined modern avenues of investment increase the opportunity cost of holding cash instead of putting cash to work in other enterprises.

Maybe people SHOULD hold cash, but even the wealthy don't seem interested in hoarding federal reserve notes (I guess that's cash?) in vaults in their homes.
