“Instead, we’ve been subjected to the equivalent of three-term congressmen with enormous egos whose interest begins and ends with popular reelection instead of looking out for their states.”
And you can blame the states themselves for that - at least 38 states (3/4) ratified the 17th amendment, so perhaps they were not so concerned about safeguarding their own powers.
Personally the amendment that I consider by far the most damaging and the one that has directly led to the unbridled tyrannical growth of government and to it controlling every aspect of our lives is the 16th - when it gave itself the right to every penny that we earn, and as a consequence the right to know and control every aspect of our lives.
Making a mistake is one thing. Letting it go uncorrected for so long after the damage is so evident, is worse.
