A shocking amount, and it’s well spent, because it literally underpins everything else. The stability it provides (or rather, provided in the past) is what made America so appealing to build and invest in in the first place.
That was also generous and includes all transportation - not just roads.
So yeah, I’m thinking defending current tax level or tax increases using these examples is not in good faith. You’re picking only The most popular programs (do we like police now?) and ignoring the other 85%.
Personally I'd happily decimate the military budget. Social security however is very popular. As is Medicare.
If you want to convince people taxes are important honestly you need to do it with Medicare. Social security, and military.
