Detroitification

Imagine a city that in 1950 was home to 2 million residents. Over 70 years many people have moved away and now the population is only around 600,000 people. The remaining population still lives in the city, but there is less density, greater distance between population centers, etc. This makes the delivery of utilities and the deployment of crucial services like road paving and snow removal more difficult. The cost of maintaining an infrastructure meant for 2 million people on the tax dollars of 600,000 people becomes almost impossible to do.
