US National Debt to GDP ratio is 130%. Currently $27.8T in National debt and $21.3T GDP (not counting another $3.3T in debt at the state and local levels, which puts the total debt to GDP ratio closer to 150%). At some point this breaks. There needs to be a bit more thinking about costs vs. benefits before signing any more multi-trillion dollar debt inducing bills (including tax cuts and stimulus). So far I will argue that the stimulus bills of 2020 cost more than the benefits they created because they were mostly pork, and we can't afford more.
