Thanks for your honest questions regarding Detroit. As someone who has lived in the area my entire life, I can understand how the changes in Detroit seem very exciting from an outside perspective. To give a quick answer to your questions: a) yes, it is an oversimplification of a complicated situation, but don't let that deter you from our amazing city; b) While Detroit is "up and coming", and places like Downtown are quickly becoming vastly overpriced, that doesn't mean there isn't a place for everyone. Detroit is a very, very large city and there's definitely a place for people of various socioeconomic backgrounds to settle in and try to make a positive impact in their neighborhood. But it all depends on what your'e looking for in an urban experience and your comfort level with a city that doesn't necessarily fit the mold of other American cities of its size and nature.
I hope this helps just a bit, and please reach out (I'm not sure exactly how and I'm hesitant to put out personal information on this site. Perhaps you know of a way to communicate?) Detroit is lovely, unique, messy in the best ways, rich in culture, and in my opinion one of the most American experiences you can ever have.
