The only places that have “good” infrastructure in the US are in rings around cities where the development has been fairly recent so the roads and all haven’t had time to degrade. Outside of the ring you have rural areas and they either have nonexistent infrastructure or what they have is dilapidated. Inside that ring you have older parts of the city that get neglected and usually the more non-white it gets the less resources are spent on infrastructure so it just gets worse.

Unfortunately, the people who live in that ring of good infrastructure tend to also be who American society caters to (middle class and rich white people).
