Breathing new life into the 10th Amendment

Universal Healthcare…Maybe in Palm Beach or Newport Beach.  But for most of America the economics just do not work out.  Since 1942 the Interstate Commerce Clause and the Necessary and Proper Clause has eclipsed the 10th Amendment.  What limit is there to the power of  the Federal Government?  Decentralizing power makes more sense than ever.  States are now more capable of self-governance than ever before.  The need for for a strong central government is limited to national security and perhaps some environmental concerns between the states.  The conservative members of the court have built up precedent to allow them to take the next step.   Will they opine in a narrow fashion or will they curb this out-of-control interpretation?
