Yes, History does repeat itself because it's the same critter making history - us.

I've often pointed out that the critter that stood in the Roman Coliseum screaming for blood is the same critter standing in Tiger Stadium screaming for blood.

However, I don't think we will have a repeat of the Great Depression. There have been some safe guards put in place since then (FDIC, etc).

One of the nice things about redundant-history, if one is observant and kept awake during history class, one can anticipate what is coming and make adjustments accordingly.
