Barely 30 years ago Beijing was the only city which had the subways in China, just one line and is very short. Now almost all China first, second and even third tier cities have massive subway systems which Shanghai and Beijing rank No.1 and No.2 in the world in length, while in US, rats still run around in the New York subway where piss smell is forever present and tracks look like sewage tunnels.
30 years ago there was not even one highway in China, now China's highway length is far ahead of any others on this planet, What US has been doing except for waging wars around the world?
Many people are marvelled at how advanced US fighters or carriers are, but what do those weapon do you use everyday when you go to work and come back home even if you are an American, what do those weapons have anything to do with your daily life and commute?
