why are cities across the river from cities on a state line often

[freepcrusher]

get a bad rap?

Examples:
St Louis>East St Louis
Philadelphia>Camden
Omaha>Council Bluffs
Cincinnati>Covington
KCMO>KCK

Now obviously Council Bluffs and Covington are not the same as the other cities mentioned and are not particularly violent. But in those metro areas it has a sort of "wrong side of the river" feel to it and Council Bluffs is nicknamed Counciltucky. Vancouver, WA is not actually a bad place at all, but even that city has a reputation as being the redneck part of the Portland area.
