Do smaller cities really need skyscrapers?

REPORTEDLY, about 230 skyscrapers will be finished this year around the world, with more than 60 percent of them in China. Changjiang Daily comments:

Ultrahigh buildings accommodate more people per unit of land area, and have become a symbol of modern cities. The urbanization of China means about 300 million farmers will enter cities in the foreseeable future. So building more skyscrapers seems an effective solution to address the imbalance between insufficient land supply and huge influx of new population.

However, the shortcomings of high buildings are obvious. They are much more expensive to build, consume huge amounts of energy, create serious light pollution and very difficult to reach for firefighters and rescuers in emergency.
