When it comes to trashy neighborhoods is it all about the money?

I have not lived in any well-to-do, or rich neighborhoods, most have been low-income, or working class neighborhoods. More times than not, those neighborhoods of low-income renters are trashed out far more than those neighborhoods where people earn more, and/or own their property. In the ”better” neighborhoods I don’t see abandoned sofas, lawn chairs, busted VCRs, bags of trash, discarded bike frames, abandoned shopping carts full of junk, and trash in the gutters, etc. Is there a connection with neighborhood pride and money earned? Is it because the ”better” neighborhoods there are more property owners so they pay more attention to their property being trashed? Neighborhood for neighborhood, (at least in larger cities), why are a greater amount of lower income neighborhoods that are trashy compared to richer ones?
