It is exactly because the Founding Fathers could not see the future that the U.S. Constitution has an amendment process. It is difficult to argue that the commerce and general welfare clauses (relative to the founders' original intent; read the Federalist Papers) have been utterly abused to expand the Federal government at the expense of the states and the people.
We have the Supreme Court to thank for this state of affairs, with the real damage starting during the New Deal era, when they could not stand up to Roosevelt's threats to expand and stack the Court. (On a somewhat related note regarding expansion of the Federal government, modern economists seem to be equally split on whether the New Deal turned a bad recession into the Great Depression or not.)
So, if health care is supposed to be "right", then why not add an amendment to the U.S. Constitution making it so. Ditto Social Security. Otherwise, give this responsibility back to the states where it (currently, without changing the Constitution) belongs.
My biggest complaint with the Federal government is that much of it is simply unconstitutional. Also, a Federal bureaucracy seems to add a lot of wasteful "friction" to the tax dollars collected. Wouldn't they be better (more efficiently) spent if collected at the state level and spent in that state?
