FDR screwed this country when he started tweaking the scope of the commerce clause in his effort to make the great depression last as long as he could.
Now it is used to justify micromanaging just about every facet of business. What FDR did also changed the meaning of the word "regulate". It used (and still does in some cases) mean to equalize. Now it means exert excessive controls over business. This is why, several years ago, the Feds came down hard on an Amish dairy farmer who lived near a state border. When it was found out that he had customers across state lines the Feds, nor absolutely no reason at all, came and shut the farm down. They took all of the cows and equipment and left the farmer with no means to earn a living.
