If that is so, then every bit of government regulation of business is unconstitutional.
That is correct.
Newt Gringrich "hinted" at this concept of "unfunded, federal mandates," in the early 90's when stumping for Republican control of the House of Represntatives.
We, as citizens, are to blame. We have not held our elected representatives and senators accountable for their unconstitutional behavior.
The good news is that the inaction of accountability by we fellow citizens was more a result of ignorance than intent.
It is only in the last 10 years that I have taken the time to read both my state and the federal constitutions so I could correctly exert my rights of freedom and liberty against the socialist/communist fellow citizens.
I surely was not taught "civics" in school from the presumption of liberty, nor has anyone else.
