Just put an "expert" in front of them, let's call them "Expert D" and half of the voting populace will be convinced of the necessity. Combine that with a second "expert", "Expert R", that asks for a sliver less, and the other half of the populace will immediately go to arguing with those who favors Expert D's advice. This may go on for several months until a compromise is "hammered out"... and then everyone is congratulated for the compromise. For those at the top it's like taking candy from a baby. Needless to say, success breeds imitation and over the years, every industry and every field of expertise has become much wealthier going to the politicians at the capital and putting on this theater... than figuring out a better way is looked down upon.
The problem is... this has gone on for 100 years... and the giant vault of money that represented the economic wealth of the American economy is practically empty. The final scraps now are being fought over fiercely. But that is a fool's game and the fools are out in numbers!. Anyone willing to step back and look at the system will realize that the system is so unusable that it's foolish to use it for anything. Like a fire hose that has so many holes in it that no matter how big the fire truck pump... and how massive the water supply... only drops come out the nozzle at the fire.
