SCOTUS is not supposed to be subject to the will of the people. We already made that mistake with the 17th Amendment, which made senators subject to the will of the people in a State, rather than the State itself.
Repealing the 17th would do more to address the imbalance of power than anything else, IMO. It is the one amendment that couldn't be cheated on.
Maybe so, but it's the one amendment almost guaranteed not to pass. Can you imagine people anywhere in the U.S. voting to eliminate their right to vote?
