I think there’s a less than 50% chance that Roths get taxed. The majority of middle & upper class voters have them, and with more wealthy people converting to Roths (and paying conversion taxes), there’s a lot of political donors opposed.
Anyway, I look at it as a tax hedge. I’ve only got 20% of my money in it, so it’s not that painful if they do tax withdrawls. And it offers a lot of flexibility vs. 401k withdrawals for minimizing taxes.
