It Certainly Couldn't Hurt

"If you leave your money with the big banks, they will use it to pay lobbyists to keep Congress from fixing the system."

The Move Your Money project is a nonprofit campaign that encourages individuals and institutions to divest from the nation's largest Wall Street banks and move to local financial institutions. Little has changed to prevent another financial crisis or to end 'Too Big To Fail,' and with Congress unwilling to act, we are encouraging individuals to take power into their own hands by voting with their dollars and no longer contributing to a financial system that has led our country astray. We are a campaign that gives people real, concrete actions they can take to create a more sane, stable and localized banking system
