Absolutely incorrect. If we removed every single bit of off-budget, non mandatory spending....we'd still be running around a $43 billion dollar DEFICIT.The reason why the budget has a deficit is because of ON-BUDGET spending, not SS which is off the budget.
SOME years it reduces the deficit, and by an infantismal amount. For instance, the total surplus of SS over its entire existance is 2.4 trillion...only 1 trillion more than this years deficit ALONE. You can also make that argument while ignoring that the trend you are so leaning upon is set to shift over the next 20 years as SS starts to apply to far more individuals and we begin, as the CBO said would be the case this year, to run a deficit rather than a surplus with regards to SS.You can talk about total spending vs total revenue, but I am free to point out that SS reduces the deficit.
