the Tenth Amendment, the last item of the Bill of Rights,
makes it crystal clear that powers specifically not delegated to the
federal government in the Articles (or later Amendments) are NOT
AVAILABLE for use by the federal government. Here's the text:

" The powers not delegated to the United States by the Constitution,
nor prohibited by it to the States, are reserved to the States
respectively, or to the people. "


umm, no, they have the previously mentioned power to spend money like a
drunken sailor. It is up to US to stop them. WE choose not to. All money
ends up in some persons hand for some reason or another, why it ended
up there really is not a constitutional issue.

Unfortunate, but true.
