Enact what Sen. Chris Dodd referred to as "clawbacks." I.e. require disgorgement of everything these bastards have accumulated up to the total extent of the damage they have caused, including their real estate, cars, boats, stocks, bonds, safety deposit box contents--everything! For those who have expatriated their profits or themselves, make arrangements with foreign countries for them to expropriate those assets, using that portion they recover as required to cover losses to their citizens and returning the remainder to the USA. Do the same for them.
As a final sop, qualify them for SSI as being emotionally disabled and allow them to receive food stamps. Call it tough love. It would give them the basis in personal experience to develop compassion for those less fortunate than they are. There would still be many of those.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
