You and I live on different planets.
I have seen many areas that were nice go downhill fast.
What happened was that a few “bad” families moved in—then the crime rate went up—then the good people started bailing.
I have seen it with my own eyes here in CT.
You give me ten criminal “families” determined to rip off and terrorize their neighbors and any community will go down the toilet in a hurry.
The most common example were public housing projects. Once single black moms moved in with their “good boys” they went down the toilet in a hurry. As long as the “good boys” live there hope is gone.
Actually this time you got it right. Yes “bad” families move in, people not taking care of things. Those aren’t gangs, those are people who don’t give a crap.
Remember the Projects started nice. But nobody took care of them.
See you went from blaming gangs, who are actually the last people to move into a spiraling neighborhood, to residents who don’t care. We’re now in complete agreement.
