A bit about the Constitution

Show me in the Constitution where this nation can not legislate social programs, Dennis. For your information, the primary function of the Constitution is to describe the three branches of government and their responsibilities. Aside from a few basic human rights presented in the amendments, the Constitution does not legislate.
For example, nowhere in the Constitution is there a law against murder - and aside from some liberties taken by the military in their 'uniform code of military justice', the only laws against murder are by the states which have their own laws.
You might consider also that a very loose interpretation of the Constitution allows anyone and everyone to bear arms (guns, etc.). The Supreme Court has ruled against that interpretation of the 2nd Amendment a couple of times, but even so, did you know the amendment does NOT involve states rights and that any state, California, for example could, if it wished outlaw guns? The states are not bound by the 2nd Amendment.
I'd suggest that you study the Constitution more closely, Dennis. This is not political opinion, but fact. The Constitution happens to be a rather simple document and not really a body of law. It is an excellent document which allows for all sorts of interpretations which fit the times as they change.
Social programs are enacted either through the states or by the Congress which have the exclusive right to enact laws. As long as the laws don't violate the very few restrictions in the Constitution they are certainly legal and Constitutional. In fact, there is probably no law on the books which is unconstitutional because ALL laws are generally opposed by someone and if challenged and found to not be constitutional, they are rescinded by the courts.
