The modern world tells us, always and everywhere, that bigger is better: GDP must continually grow; cities must perforce become higher density, and literally higher; globalism good/nationalism bad. Greater efficiencies can only result from growth.
Huh. I haven't heard about that last one so much.
Over 5.7 million people live in Atlanta and its metropolitan area. We are in the middle of a building boom. More people, more jobs, and more luxury cars than I can ever remember seeing in my lifetime. Atlanta also has a sales tax of eight cents on the dollar. On November 8, voters approved an increase to 8.9 cents on the dollar.

I voted against the sales tax increase because I figure with an 8% sales tax and thousands of people moving in, you can find the money for infrastructure somewhere. If you're interested, you can get a copy of the City of Atlanta budget for FY 2017 here. I'll summarize: the City is rolling in dough. And like just about any other enterprise, personnel is the biggest expenditure. Most of this projected $2.8 billion will go not toward actual infrastructure, but to the human resource and logistical tail for infrastructure.
So it seems that even with more people moving in and paying property and sales taxes, the City must still raise rates because it has to pay more people and build more infrastructure to manage its growth. Unit costs are going up, not down. Diseconomy of scale.
