are contradictory.

A better argument would be: "Increased education and welfare spending leads to more productivity and the added cost is offset by the increase in taxes due to the productivity gain". Or more simply: "Education and welfare are good investments".

Now we can have a serious conversation about the economic impacts of this kind of investment. But to market it as free is irresponsible. It it not free. At best we get more out than we put in, but by definition we must put in something.

That was the point of my original comment. Everything has a cost. Even an investment with a nearly guaranteed return comes at a cost and has a certain amount of risk associated with it.
