I mean, yea? CA has the highest real poverty rate (SPM) in the whole country.
Some of that won't translate as well to road quality due to the fixed cost portion of road repair (because the OPM rate isn't the highest (though still quite high)), but some of it will due to the not fixed cost portion (labor, etc).
But it definitely affects prioritization. People won't care as much about road quality relative to other things.
This does not make a great argument for California. It appears as a failed state compared to others.
