The spending is a symptom. The underlying and Unconstitutional part is that we are using fake currency, faux money, debt-based, principal ALWAYS accumulating, interest always being paid (think IRS 1040). Federal Income Taxes do NOT pay a plug nickel for any federal program (see Grace Commission report).
Constitutional money has been tried, to no avail. Have had it for short periods (Lincoln, Kennedy). There is an effort today to re-institute Constitutional Money (see 2025 Treasury dollars, usdebtclock.org).
Constitutional Money:
Art 1, Sect 8:
To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures;
To provide for the Punishment of counterfeiting the Securities and current Coin of the United States;
Art 1, Section. 10.
No State shall enter into any Treaty, Alliance, or Confederation; grant Letters of Marque and Reprisal; coin Money; emit Bills of Credit; make any Thing but gold and silver Coin a Tender in Payment of Debts; pass any Bill of Attainder, ex post facto Law, or Law impairing the Obligation of Contracts, or grant any Title of Nobility.
