Missouri Pay As You Go
The Sophorist
links to a person who links to a story about Missouri state government offering taxpayers the opportunities to add money to their taxes for common programs:
If passed, this fund would allow ordinary citizens and every special interest in the state to contribute additional tax dollars to their favorite cause, program, or policy. It would afford the average hard working taxpayers the luxury of avoiding to pay higher taxes in these difficult times, but permit all those people and interests who believe state government should be bigger and should allocate more resources to contribute generously.
On the whole, I think it's a good idea, but I would hate to think of how much "Give Us Money" advertising the programs would spend the extra money on.
Were the programs to receive enough funding through the opt-in tax payment plan, I suspect that the state government would start reallocating that percentage of the program's original funding to other, newer, and more profligate programs.
