In general, cities like Chicago and LA have lower crime then they have in decades, have higher property values then they have in decades, and are contributing a great deal to the economy on a per capita basis. Cities in the US in general are doing quite well right now.

In the 1980's, people often argued that cities were "decaying" and all that; the opposite is true now, young people are moving back to cities in large numbers, probably because the high crime rate that drove people out of cities 30 years ago is now way down.
