Proposes a constitutional amendment relating to the creation of a sovereign wealth fund for the state of Missouri

HJR 189 proposes creating Missouri's "Show-Me Prosperity Fund," a permanent endowment designed to eventually eliminate all state taxes. The fund would grow through investments, and only after the state treasurer confirms sufficient annual investment income covers current tax revenue could it fund tax eliminations. Strict rules prevent using the fund's principal, limit annual withdrawals to 2% of its 5-year average value, and require voter approval for tax changes. This would directly affect all Missouri residents by potentially replacing state income, sales, corporate, and other taxes once the fund meets specific growth targets.
