Keep making things up.  Reducing the amount you can put into your 401k is basically a tax increase.  Currently, I max mine out.  That means my taxable income is reduced by $18,000 a year.  If they go through with this, then my taxable income will go up by $15,600 a year.  Tell me again how that isn't a de facto tax increase?  Who is pushing for this?  Hint, it isn't the Democrats.  As for taxing Roth proceeds, that will be the next thing the Republicans change in order to pay for their tax cuts for the wealthy.  But, by all means, keep blaming the Democrats for what the Republicans are doing.
