We've allowed our reps to vote themselves very enviable benefits. A letter in the local paper was pitching for immediate termination of all special privileges for congresscritters. Immediate termination of retirement with refund ONLY of what they had contributed, and termination of health insurance. (go find your own.)
The writer was figuring that by the next election, many would not run for re-election.
I believe most of them have become absorbed in their own self-importance. I don't know how to bring them down a notch other than voting them out of office.
