Five aspects
The payroll tax is uncapped and applies to all compensation — wages, bonuses, equity, deferred income. It provides the largest single funding stream for Distributed Healthcare, replacing fragmented current funding through FICA-Medicare, employer health premiums, and employee premium contributions.
The new payroll tax is the largest single source — not "most of the cost." Federal general-fund redirection from current Medicare, Medicaid, and VA budgets provides comparable revenue. Federal Medicaid absorption brings additional flow; states retain their share. Supplemental tiers are separately priced in the regulated market — never bundled with the payroll tax. AHQB cost controls reduce baseline expenditure compared to current US healthcare spending (18.0% of GDP, CMS 2024).
