That would imply a premise that the federal government is granted all powers not explicitly denied to it in the Constitution, and that is dead nuts wrong.
That's not at all what it implies...
There is one branch that has that power, because it is in effect the voice of the people.
That branch is the legislature who has oversight over everything and only uses a small percentage of it's powers.
That is one of my issues. Congress punts the ball entirely too much, but when they do, SCOTUS recognizes it and that is how you get idiot law from the nine...
