UPDATE 11:20AM: accused of Detroit "poverty porn", see response below. As you may have noticed, this blog sees America itself as an interesting development laboratory. Others seem to agree, as a new report applies the Human Development Index to the US.

As further recompense, here is a nice happy positive picture of the real "downtown Detroit."

It's going to take more than a few happy pictures to fix that.
Have fun on your own exploring Third World America on this great site.
