Has there been much change in the large, U. S. urban areas since the turn-of-the-century? Or, is it all still very much the same? Why do you feel this way? If you find inadequacies in today's urban condition, what can the government do to improve the situation?
There has been a lot of work done in many urban centers across the country in an attempt to revitalize these communities. As mentioned above, the hope is to attract people back to these areas to shop, to eat, to be entertained, and to live. This doesn't address the largest cities and the worst of the projects, but it is a trend--or it was, until the economy slowed this kind of revitalization.
One positive item in recent news about urban areas is the increasing number of people--many of whom are in their late twenties--who are taking up residence in the city rather than living in suburbs. There are new residences being built, new restaurants, clubs, etc. constructed to appeal to these young people who work downtown and can contribute a very positive influence upon the city's economy and places of interest and entertainment.
