what is the main difference between sities those which have more priority from goverment

What is the main difference between cities with more priority from the government, and cities with less?

In my opinion, the main difference between such scities is the more intensive financing of such spheres as construction and maintenance of city roads, construction of new modern residential and office buildings, creation of lawns and green spaces, and the preservation of the monuments of architecture architectural monuments. Also, you can see clean streets and a lot of boxes bins for rubbish everywhere. And opposite - in those cities those, which don;t have priority from goverment - often you can see dirty streets, rubbish is on the street, old roads and buildings, the destroyed monuments. So, the common trend of the improvement in the quality of life in such cities is the main difference, I think.
