A society in which it’s everyone for themselves, that refuses to care for one another, is no society at all. Then everyone acts shocked and horrified at someone who understandably snaps, like modern western culture doesn’t run entirely on schadenfreude.
That was the crux of the idea of a social contract, which is long dead in the US. Now people line up to revel in the suffering of their fellow citizens with “well you were stupid to do xyz in life, so you deserve your suffering haha.”
This is a bit dated but shows that 41% of road upkeep on average is paid for by gas taxes (and other fees). So yes while they may have some tax paid on fuel (that they have likely negotiated down via bulk purchase), they’re not even paying for half on average.
Edit - just to include given we’ve seen landmark inflation over the last few years it’s likely the share of taxes on upkeep has gone down.
