Pretty weak. Ghetto still means a place where Jews or poor people
live.
The fact that a few rappers embraced the term does not change the
meaning ... unless you think "nigga" is now OK since Larry Wilmore
called the president "my nigga".



There are plenty of references that expand the meaning of ghetto beyond
what you think it means.


Point is, in normal conversation or writing, even by the "highly
educated" ... "Ghetto" has only one normally used meaning.
