House Republicans are taking aim at the financial reform law, passed earlier this year by Congress, that includes limits on banks' using their customers' money to buy and sell risky investments. It's called proprietary trading and while some experts say it puts the whole economy at risk, Republicans say the real problem was falling home prices and poor lending standards. Temple economics professor William Dunkelberg says big banks did rely too much on trading risky assets "rather than on traditional banking and paying attention to the quality of assets that they purchased, like mortgages."
