That's the way to go about it. Imprison them all, take all their benefits, confiscate their property, make them pay back every single penny they have fraudulently obtained from hardworking tax payers. Stop bailing out private banks by using tax payers money.
When it comes to bankers, I would gladly re-introduce a death penalty. That would make them think twice before they embark on yet another fraudulent Ponzi scheme.
