The people who founded the country did it with the idea that government would be a relatively small and unimportant part of everyone's lives, except for the few that were actually policitians. The whole idea was that people would be free to run their own lives and sink or swim by their own decisions, helping their neighbors when needed, learning from their own mistakes, trying again etc.

The government was there only to do things private citizens or groups could NOT do - dealing with foreign countries, national defense, dispassionate criminal pursuit and prosecution, setting national standards etc. And even most of those things were to be done at the most local levels, with the Federal govt's purpose only to handle the matters that even local or state govts couldn't.

The Constitution was written accordingly, giving the Fed only the powers that"the States or the People" couldn't handle at all. And that wasn't very many. It was forbidden all else, though the states and people had all other authority to do the rest.

So many parts of Obamacare (and much of the rest that the Fed has intruded on today) flies in the face of those ideas.

This is a good thing to keep in mind - each time you examine some new (or not so new) thing the Fed govt is to do, this will give you some pointers about whether it is unconstitutional.

And remember that the issue is not whether you think the govt can do it BETTER than the People. It's whether the people can do it AT ALL. If they can, however imperfectly, then the Fed govt is forbidden to "help".
