And you would be wrong. The 14 th amendment started the ball rolling and as in Government will do, and we warned about by the founding fathers , it has seized more and more power.
Illegally I might add. The Commerce clause is used to justify any and every thing, INCLUDING the claim that Education is a Federal power. There is no intra State Commerce any more, every facet of commerce is now controlled by the Federal Government by claiming the commerce clause covers it if there is any chance any thing was ever possibly, maybe involved in some cross state transaction.
If you produce items IN your State and only sell them IN your State you still get hit, if you ship by any carrier that ever does any out of state business or if any thing, any tool any material, any thing you have in your business come from out of State.
Paper, pens, filing cabinets, it doesn't matter, the Federal Government claims if you buy them and then use them in your business that makes you involved in your further business in interstate trade. That IS NOT the intent or purpose of the Commerce clause.
