Well considering that the toxic debt is actually trillions of dollars in value some even saying it's up to 8 trillion, 700 billion will have minimal impact of only delaying the inevitable, in fact potentially worsening it long-term.
If the American people were buy off ALL the toxic debt (if the maximum is 8 trillion for example), it would cost at least up to $21,000 max per taxpayer over the time period it's paid. This bailout is setting a dangerous moral precedent to banks that they can get away with it at taxpayers expense and real question is that, how much of the toxic debt will the government need to buy out before the system stabilizes (if at all)? If anything the bailout would allow more debt to accumulate leading to an even larger collapse in the future.
