Another very marxist concept from the founders:

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.

Which is what I was referring to when you brought up the specter of Marxism.

If providing an education isn't promoting the general welfare, I don't know what is.
