I'd support a protest at The Federal Reserve. Those protesters are mad at the wrong enemy.
While I too would prefer a protest against the Federal Reserve since that is really the source of corruption, Wall Street is absolutely a good target. These motherf***ers all went bankrupt then got the government to bail them out, stealing from the many to enrich the few. It really epitomizes what is wrong with america.
Blame the criminal organization which hands out other peoples' stolen money. Don't blame Wall St. for taking that money when offered to them. Remember also that some financial institutions were FORCED to take the money, so that the vulnerable ones would not be known to the public. The blame lies squarely with Washington, or perhaps with the people who vote those fools into office.
