So diversify your regulatory risk…half in traditional, half in “Roth”. If your work only allows traditional 401ks, contribute to Roth IRAs and rollover to Roth IRAs whenever you change employers.
I’m of the opinion that Roth IRAs are actually at greater risk of demagogery: they were a vehicle for people to pay taxes upfront at what they bet to be lower rates than what they would get at retirement. So then people will be complaining that wasn’t “fair” somehow, and then they’ll be taxed on the way out too.
Not to say they wouldn’t do this with traditional 401ks/IRAs too, but here I’m hoping for protection by a the increased likelihood that more people who vote have savings of this type, and would thus be more likely to vote to protect them from further erosion. But to check this premise, I’d have to know which class more assets have been parked in. Any ideas how to research this information?
