Why is it difficult to do traditional industries in all walks of life now?

Traditional industries: cement, coal, steel and other high-pollution industries have overcapacity, and supply exceeds demand. However, this industry has absorbed a lot of labor. If these workers lose their jobs, society will be unstable. Therefore, the support behind the country is to print money to build railway and highway infrastructure and consume these excess capacity. Although maintaining 7% GDP growth, you want to build roads without cars, and the subway is very deserted. These are all thrown away money.

Now most consumer goods have online shopping, and even taxis have been robbed of business by Didi taxis and Didi carpooling. The Internet can keep the cost very low, and it is really difficult for entities that want to rent hydropower and coal.
