Oh c’mon. The change meant that when an employee is doing their induction paper work instead of checking a box that says “I opt into the 401(k)” they instead checked a box that said “I opt out of the 401(k)”.
The knock against the 401(k) is that most of the benefits flow toward high earners who don’t need help saving.
That said, in recent years Congress has worked hard to make sure lower income people don’t get any tax deductions. The 401(k) is one of the tax deductions lower income people can still get, and with no hassle. It is an easy way to save money, and the immediate tax deduction makes it more affordable for people who need the help.
