Nothing will be like before...
I doubt it. We forget things when we don't deal with them everyday. After the Bank Fraud of 2008, some old rules regulating bank behavior were restored, but not nearly all of them. And those will likely be lifted again. At one time, I believed the US would stop meddling in other countries affairs after the Vietnam debacle, but we didn't. Whoever said, "We study history so that we don't repeat it," was talking out of his bottom. Things will return normal. I wish they wouldn't, but they will.
