I think it'll have to happen fast and not incremntally, otherwise too many people will move their remaining money out of the system entirely.
So then they "voluntarily" give the government an instant boost of 10% penalty with 25%+ typical in taxes for 401k or IRA holders? Cha-ching!
Even threatening it to get people to put less into their 401ks and pay more in tax this year might be what they really intend.
On Mondays, Wednesdays and Fridays I think they want to steal everyone's 401k. On Tuesdays, Thursdays and Saturdays I think they just want to suppress them to increase current year taxes.
