Congressional pay would have been reined in had they ratified this proposed article in the Bill of Rights:
“No law, varying the compensation for the services of the Senators and Representatives, shall take effect, until an election of Representatives shall have intervened.”
An informed electr\orate would vote the miscreants out if, for example, they gave themselves an 8% raise and kept SS COLA flat.
Had a “much smarter” than I am friend suggest that Congressional pay be based on the ‘Economy’, if we balance the budget, good. If there is a surplus better, etc.
That is beyond my pay grade but there are people that capable in doing such a system.
That was ratified-- eventually-- in 1992. It's now part of the Constitution, as the 27th Amendment. Hasn't made much difference, though.
