I think that the original concept of the interstate commerce clause has been interpreted out of existence and given the Federal Government almost unlimited powers to do anything it wants.
My amendment is to try and restrict this power and would read as follows:
Section 1. Nothing in this Constitution shall be construed as to give Congress any power to abridge the freedom of Commerce, Industry, Production, Medicine or Education, or any of them.
Section 2. , No monies appropriated by Congress shall be paid out as a subsidy to any individual, group, or for any establishment of commerce, Industry, Production, Medicine or Education, or for any product or service, unless agreed to by a 2/3 majority of both Houses of Congress, but any such subsidy shall not be for a term longer than 1 year, or until an election to the House of Representatives shall intervene, whichever shall come first.
