I get the gist but those two pictures of Detroit are of completely different places.

First one is of downtown, which still looks like that (without all the people, mind you. It's either abandoned or turned into Truman Show esque prop stage) and the second is probably of some neighborhood like a couple of miles from downtown.

I know it's a meme, and it's more or less accurate, but I will say I'm not a huge of using Detroit as a comedy bit when nearly everyone in the US constantly shits on it, usually with obvious racist undertones.
