This general idea is what scares me about roths in general.
I am saving a decent amount (11k a year) in roth because of how it works now. If in 2, 5, 20 years it starts losing the benefits (no RMD, etc. etc.), then it will mean I made a bad decision and should have gone pure traditional.
In life in general, planning ahead beats living for the day. In tax policy... seems like maybe we should live for the day. if traditional IRA is better RIGHT NOW (because of the tax benefits), then do it. Would suck to suffer with a roth then get hammered later as an easy way to fix a government budget mess.
