Providing for the general welfare is in our Constitution.
Read the Federalist Papers. General welfare had NOTHING to do with the modern understanding of welfare, as much as today's progressive leftists wish it did.
If it did, there would be no point in enumerating powers. Read:
To illustrate how enumeration limits power, consider the General Welfare Clause of Article I, section 8. Were the passage containing that clause to be read simply as authorizing Congress to tax and spend for the general welfare, as some read it today, Congress would have been granted all but unlimited power and the enumeration of other powers would have been to no purpose. Thus, the passage must be read as permitting taxing only for enumerated ends; and the clause restricts such funding to the general welfare only, not to the welfare of particular parties. Similarly, the power given Congress to regulate “commerce among the states” could not have been a power to regulate anything that “affects” commerce, which in principle is everything, for that too would have made pointless any limits imposed by enumeration. Rather, the Commerce Clause was meant primarily to restrain state power: to ensure the free flow of goods and services among the states, Congress was given the power to regulate such commerce—to make it “regular.” Those limitations are reinforced by the Necessary and Proper Clause, which limits the means available to Congress to those that are “necessary” for executing enumerated powers—without such means, the enumerated powers could not be executed—and “proper” for a government dedicated to liberty.
