"I'll fight for a new tax-free way to help you save and build a bigger nest egg for your retirement. I'm talking about something extra that you can save and invest for yourself, something that will supplement Social Security, not be subtracted from it. But I will not go along with any proposal to strip $1 out of every $6 dollars from the Social Security Trust Fund and privatize the Social Security that you're counting on. That's Social Security minus. Our plan is Social Security plus. We will balance the budget every year and dedicate the budget surplus first to saving Social Security."
