A picture is worth a thousand words but do those words tell the truth. We need the dates when the photos were taken to compare them to present photos to assess whether this is propaganda or not. These photos without reference are just simply photos not evidence of reality.
China cannot sustain its growth without other countries purchasing the cheap manufactured products. The whole world is collapsing economically and the governments are all building totalitarian police infrastructure to manage the mass uprising. This will not work. The so called leaders are empty shells whom have lost their compassion and understanding for the common men and women. Once the corrupt regimes fall, then, we can rebuild our countries and provide jobs and benefits for all.
In China, money generated through taxation of foreign companies and imported products (like ferarris) is sent down to local municipal governments of small towns, then used for construction projects that do not need to generate rent or sales to be profitable. The construction process alone IS the business. It is not a market based real estate market. The government earns money here by renting land to developers.
I don't know why the lack of cars is considered "evidence". Only a tiny fraction of Chinese people own a car. In the US, with 300 million people, there are about 200 million cars (2 cars/3 people). However, in China, with 1.3 Billion people, only about 50 million new cars have ever been sold in the country (~2 cars/50 people). I would expect that most cities and neighborhoods would have very few cars. If you were to take aerial photos of suburban US (specifically, neighborhoods where every house has a garage), wouldn't it look similar?
