Without action the US faces a definitive fiscal wall, but Dalio's '3% solution' shows it is solvable: under the existing budget with the Trump tax cuts rolled forward the deficit will be about 7.5% of GDP, and reducing it by about 3% of GDP would stabilize the debt; this can be achieved through a balanced mix of spending cuts, tax revenue increases, and interest-rate effects, and a moderate non-traumatic mix would naturally lower rates as risk falls.
