Ah, yes. From capitalism magazines website:
Back in 1942, the Supreme Court authorized the vastly expanded powers of the federal government under Franklin D. Roosevelt's administration by declaring that a man who grew food for himself on his own land was somehow "affecting" prices of goods in interstate commerce and so the federal government had a right to regulate him.
Stretching and straining the law this way means that anything the federal government wants to do can be given the magic label "interstate commerce" -- and the limits on federal power under the 10th Amendment vanish into thin air.
