According to the Washington Post, there is a new movement forming called “take on Wall Street”.

the group expects to galvanize support for breaking up the big banks and reviving a version of the Glass-Steagall Act, which prevented the combination of commercial and investment banks. It is also expected to push for a transaction tax, which would force some Wall Street traders, particularly high-frequency traders, to pay a fee every time they buy or sell a stock or bond.
