There is no "welfare clause". The Preamble does not say "provide for the general welfare". "We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America." Promote does not mean provide. "To promote the general welfare" defines the context to the Constitution and its mandates. Nothing more. It does not grant power, it is not law, and authorizes no legislation forcing a redistribution of wealth to citizens or industry as it has been twisted to mean.
