Public budgeting as practiced is a machine for hiding trade-offs. Spending is approved in nominal amounts — flat dollar figures, unmoored from any total — one program at a time, so every advocate can argue their cause on its merits and no one ever has to say what should shrink to pay for it. Deficits absorb the difference; the fight over who actually pays is deferred to inflation, debt service, and whoever holds office when the music stops.
Here, the budget is denominated in shares, and the shares always sum to one hundred percent. Adding spending is deleting other spending — explicitly if the proposal names its offsets, implicitly and pro-rata — everything else shaved in proportion — if it doesn't. Every advocate must name their victim. That's not a hostile framing; it's the honesty that current appropriations processes are structured to avoid, restored by construction. A proposal that cannot say what it's worth more than has no claim on being funded. And zero-sum accounting is the antidote to spending-as-constituency-building — the pattern where a program distributes its supply chain across fifty states not for efficiency but to make itself politically unkillable. Under a 100% budget, every such program is visibly occupying share that something else wants, forever.
Absolute budgets grow primarily one way: the base — the taxable economy underneath the shares — grows. This snaps the incentive chain cleanly into place — chapter 7 pays leaders for durable, confirmed policy; policies that grow the productive base grow every share's absolute value, including the value of the leader's own persistence pay. Extraction shrinks the base and eventually the extractor's own dividend. The design goal is an executive class whose enrichment is mechanically coupled to broad prosperity, because decoupling those two is how every wealth pump in history — every arrangement that siphons upward while the base stagnates — got built.
One escape valve, engineered rather than improvised: hard balanced budgets are procyclical. A recession shrinks the base, forcing cuts exactly when spending stabilizes, deepening the recession that forced the cuts. So the constraint carries a pressure release — a countercyclical buffer accumulated in good years, or an explicitly voted debt exception that is expensive to invoke and reserved to the national scale, where the macroeconomic rationale lives. The valve completes the constraint instead of breaking it: the default is always 100%, and departures are loud, voted, and temporary — never the quiet ambient norm they are today.
