While Centrism your correct that a SCOTUS decision is at times considered settled law until such time as it is overturned by another case, there are many 10th Amendment cases I just cited one as an example to show where the court had veered off the path of the framers original intent and thats quite clear from Jeffersons words on the matter. I sometimes think that people often are under the impression that the United States of America when they look at it often times forget the States part and focus on the America part. No matter there are many examples if this .. Munn v. Illinois Citation: 94 U.S. 113 (1877) Concepts: Public-Private Property/FreeEnterprise v. State Rights Facts Midwestern farmers felt that they were being victimized by the exorbitant freight rates they were forced to pay to the powerful railroad companies. As a result, the state of Illinois passed a law that allowed the state to fix maximum rates that railroads and grain elevator companies could charge. Issue Whether the regulation of railroad rates by the state of Illinois deprived the railroad companies of property without due process of law. Opinion The Supreme Court of the United States upheld the Illinois law because the movement and storage of grain were considered to be closely related to public interest. This type of economic activity could be governed by state legislatures, whereas purely private contracts could only be governed by the courts. The Court held that laws affecting public interest could be made or changed by state legislatures without interference from the courts. The Court said, “For protection against abuse by legislatures, the people must resort to the polls, not the courts.” I'm also in complete agreement with caela on the fact that often times the Federal Govt. will use the power of the Federal purse to bend states to it's will as was the case with the drinking laws.
