Politically, the story would be something like this: why should you, a multi-millionaire SW engineer who hasn't paid taxes on your 401k not pay your fair share so that these other folks can spend some time with their families? After all, they were the victims of predatory lending! Close the loophole that allowed your opulent lifestyle!
And remember, 401ks are a multi-trillion dollar market of untaxed dollars. Do you really think tomorrow's politician in 30-40 years is going to miss that, never mind their constituents?
