It seems like you're referring to the slang usage of the term, which is mainly used by upper middle class youth when referring to things outside their economic class and daily reality, is pejorative, and is often tinged with racism.
the "gourmet ghetto" in North Berkeley, for example.
I also spent 4 years calling <5 floor dorm buildings "BuildingName Tower". It even caught on with other people, but that didn't change the definition of a tower.

I certainly think so too, seeing as how it is nothing but a slang term.

How rich, the guy who uses North Berkeley as a counter example is calling people out for a limited world view.
Ghetto, in its appropriate usage, isn't a slang term. It's been a part of standard English for a long time.
Word meanings are by nature fuzzy, democratic, fluid, subjective, regional and varied. So you may be fighting a losing battle to want "ghetto" to have a fixed "proper" meaning that people should use.
This is a disgusting concept and an insult to human dignity. It will turn "ghettos" in the slang sense into more genuine ghettos in the historical sense. And lansing is right to take issue with the term as it's used now, because it's become a light, casual, racist and derogatory way to talk about a certain area, which is definitely used by the white middle class as a stand in for other racist words they don't feel comfortable saying anymore.
[Edit: The fact this was downvoted in less time than it would take a speed reader to finish what I wrote is pretty much proof that either someone's got it in for lansing, or someone's a fuckin racist dipshit. Either way, fuck you.]
[Re-edit: Not only do I stand by my comment, I think the people who downvoted me are cowards. Respond if you have a response, and you speak enough English to communicate it.]
Also, now you're complaining about getting downvoted, which is generally against the rules here and will often lead to further downvotes (because you getting downvoted is always off-topic).
Personally, I think I would find some of what you're saying interesting if you presented it in a way that's more informative and actionable and less angry or defensive. Could this have a negative impact on those neighborhoods? That's an interesting question. I'm not sure if it would (most of the people who travel in the area frequently will already be avoiding them), but it's an interesting question. Unfortunately, rather than exploring this interesting topic, you decided you'd rather hunt racists, which might make you feel all high and mighty but doesn't really advance the conversation.
