Taxpayers should have a direct say over what money is spent and borrowed, in proportion to how much tax they pay. Putting such a system in place will curtail the persistent problem of ever expanding government spending.
I find this interesting for a few reasons. First, it’s different than another suggestion I’ve heard, to give voting power to people proportional to the taxes they pay. Second, it might actually work. Stripping politicians of taxing and spending power and giving it to the people funding the government would solve the incentive problems inherent in any government.
