While I can’t find a specific bill introduced, it is quite easy to find where congressional committees have heard testimony on all sorts of changes over the past several years.

Beware of Congress’s Threat to Tax 401Ks
Written By Elizabeth MacDonald
Published October 31, 2008
So I wouldn’t be too sanguine by saying that “no actual bills have been introduced,” in congress. That is often the next step after hearings.
The threat is real, as elimination of private capital is a keystone of Marxism. Besides, there’s just too much money out there to tempt the collectivists.
The first article is about the same loony professor that made a presentation to a committee. That was it. And in the ensuing furor, the committee chairman effectively disavowed her proposal.
The other two articles are about the possibility of making changes to the rules for new contributions, such as limiting them for high income taxpayers. There was nothing about confiscation or conversion of existing assets.
My point is there is no serious consideration of what some people are claiming. It is just fear porn to get you to read their blog or listen to their show. Stop falling for it, and stop repeating it.
