there was a bill in the house:
“Under the Automatic IRA Act of 2010 (S. 3760), employees that currently lack an employer-sponsored retirement plan would be offered an auto-enrollment plan by their employer. “ - Aite Group report
Don’t know what the current bill is, or how it has changed...
As this was dated August 2010 before the House majority change, this is probably dead there.
Biggest concern now is a considerable change in angle of attack, the Reid Senate and Barry's E.O. pen.
