Life would be so much better if we all lived in cities.
Forget about the crappy schools, and the crime, and the fact that people move to suburbia because they want a little bit of privacy.
Personally I think the big cities of the 19th Century are an anachronism.
People moved to cities because that is where the jobs were. But note that "were." Past tense. The jobs are no longer there. Detroit (for example) has been so universally abandoned there are people actually suggesting that big portions of it be returned to farm land.
