1. That was the whole idea of the "agglomeration economies," aka the urbanization. Bringing all the talent together into one place to make doing business easier. The urbanization is kind of big thing for the Chinese Communist Party, because it will tend to lead to there economies of scale, and development of the ecosystems for industry, factories, etc.
2. What were the factors of production? Labour and capital right? Go old school, and the factors of production was land, labour, capital. Today they added a couple more things, forget at the moment, drinking again. Land. Real estate. Look, if urbanization is a goal, you need land. Little wonder that Chinese real estate prices in the most important city clusters are through the roof. This is a byproduct of development, or precisely the direct result of the strategy of urbanization. They could not build enough housing fast enough. When it was built, the average Chinese had the means to buy, and buy, and buy more real estate, creating the entity that it is today.
That is why I do not believe this real estate issue is much of a problem. It is the tail of the dog. The tail does not wag the dog in China! It does elsewhere sometimes, but never in China.
3. Remember the trade war? Remember the Trump tariffs? Remember how the CCP devalued the Yuan just slightly? Remember that crackpot Navarro going ballistic because the Chinese did that? Haha!
The tariff, was going to make Chinese manufacturing more expensive, (see above article). But lowering the Yuan, makes Chinese manufacturing less expensive. That is what they did, they fought. If I keep my industries up and running, and keep growing, then I win. That is what those communist were thinking, because they were thinking the most hardline rightist ideology ever! How to damn make money and crush a fellow capitalist hopes like Trump!
The best capitalist in the world today probably are the communist Chinese. The future of capitalism! Haha!
