As people leave Detroit, and move into the "inner ring" of suburbs, the crime, drugs, etc. move with them, so in X number of years, people won't want to live in Harper Woods, East Pointe, Warren, etc..., but will move farther out, and the cycle will continue. I have relatives who thought their Warren neighborhood would stay nice for many years......WRONG! It is gradually becoming just as bad as Detroit, so they are looking to move WAY out...into the Thumb, but NOT Port Huron..for the same reason.
