The solution to this is obvious: eliminate the IRS. And the income tax. And most of the federal government. Spin off the actually useful bits as private non-profit foundations (or possibly even for-profit companies depending on the scenario) and let them earn their own keep based on the value they provide. A sufficiently small government can be funded without an income tax, as history shows us.
It's a recursion which has plagued the world for centuries.
The whole system can in theory be replaced with non-profit investments funds, which crowdfund social projects.
You dont even have to elect 'leaders', because citizens will be involved full time in running things (by guarding their investments) similarily to how they now waste time on Facebook.
But good luck changing anything without a nuclear apocalypse :) There are a lot of people who like the system the way it is and they won't give it up because us idealists want a better world for their children..
