The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defense and general Welfare of the United StatesNo, I've proven Congress has the power to raise taxes to pay debts, provide for the common defense, and the general welfare. "The general welfare" means Congress can do pretty much anything to better the health, happiness, or prosperity of our country, which would include welfare state government programs like Social Security. Congress can do pretty much ANYTHING it wants, so long as they can claim it will make the country better (and what lawmaker claims his law is going to harm the country?)
