Which is always a stupid take. America is absurdly wealthy. We could burn half a trillion dollars a year in a big bonfire and still easily afford all the niceties of a modern nation like good infrastructure and healthcare.

We might have to actually tax a proportional amount from ultrarich and megacorps, but I'm perfectly fine with the people receiving 70% of all increase in wealth since the 50s paying a significant amount of tax.

Who did? The worst roads in America are all (meant to be) maintained with local/state money. The road surface of the federal highways are all in a reasonable state, although many bridges are sketchy. The F-35 isn't the reason an average country road in America looks like the surface of the Moon.
