Constitution's interstate commerce clause abused

"...in 1942 the Supreme Court ruled in Wickard v. Filburn that a farmer growing wheat on his own land and for his own use was still subject to federal production limits, even though none of his wheat ever left the state. {Wickard v. Filburn, 317 U.S. 111 (1942)} The Court "reasoned" that by withholding his wheat from commerce, the farmer was affecting interstate commerce, even though there was no commerce, let along interstate commerce. This meant that private economic activity conducted for the sole purpose of self-consumption and occurring wholly within a state's borders would now be subject to federal regulatory authority under the Agricultural Adjustment Act. Wickard swept away 150 years of constitutional jurisprudence, decentralized governmental authority, and private property rights protection. And with it the judiciary seized a role for itself--the manipulation of law to promote a Statist agenda--that continues to this day." {Mark R. Levin, Liberty and Tyranny}
