It seems like China is having a steel problem.
Shanghai’s futuristic skyline—the city has more than 900 high-rises, with hundreds more under construction—is one of the most potent symbols of China’s economic rise. But the materials undergirding all that growth might be shakier than anyone can imagine. In March, the English-language Shanghai Daily reported that fully half of the steel sold to construction companies in Shanghai’s wholesale markets failed basic quality tests. Nearly a quarter of the tested samples failed tension tests, meaning structures built with them would not be able to withstand earthquakes and would be more likely to decay over time.All China needs is one good earthquake and it will solve its overpopulation problem with ease. And think of it. They will have a huge building boom to follow keeping people employed.
It would be like having a war only better. The necessity of spending on explosives and their delivery systems would be greatly reduced.
