The decision states face of whether to expand Medicaid to non-disabled, working-age, childless adults—the Affordable Care Act primary expansion population—involves tradeoffs. These tradeoffs include higher taxes, reduced spending on items like education, transportation, or infrastructure, or reduced spending on other Medicaid populations such as the disabled, children, or the elderly. The ACA funding formula allows states to pass a much greater share of the costs of covering non-disabled childless adults to federal taxpayers, but the tradeoffs still exist.
