Replace the Glass-Steagall Act in its entirety, to separate investment banks and commercial banks.
Why is this important?
Ever since the disastrous crash of the 20's and 30's, we enjoyed the protection the Glass Steagall Act afforded us. That Act kept "investment banks" and commercial banks separate, so that "investment bankers", or gamblers, could not gamble with our mortgages and business loans.. When the Act was rescinded in 1999 our current financial troubles began, because it allowed "investment bankers" to gamble by devising risky loans, disguising them as low-risk, and passing them on to unsuspecting banks and other investors. The new buyers have the risk of losing their money and many of them have lost from the foreclosures and other failed loans.
