I can take a stab at explaining why this is:
China's economy has been experiencing wild, wild, Will Smith Wild Wild West growth for the past 20+ years, like 8-14% year-over-year. Most of this growth has come from industrialization, the transformation of China from a nation of subsistence farmers into a manufacturing center. China takes in raw resources, processes them, and then sells them to the world, the same trick (sort of) that Britain used with her empire during the Industrial Revolution. Anyway, the Communist Party of China likes this growth, because, well, not only does it mean China Will Grow Larger, but because a wealthy people is a happy and loyal people.
Ever since about 2011, however, the growth has been slowing down, slowly but surely. We're approaching *only* 6% now (keep in mind this kind of growth would be considered an economic boom in any Western country, but in China, it's shamefur dispray.) In my view, this is because of two factors:
i. China's population is getting old - in hindsight, the whole One-Child policy had some bad side effects - increasing the number of grandmas and grandpas each worker has to support economically.
ii. China's becoming sufficiently 'modern', running out of areas it can un-fuck itself in (building modern factories and ports), which was a major source of growth.
This is unacceptable to the CPC. If the economy stops growing, people will become shiftless, China's off track to becoming a superpower and fucking up the US, economists might even lose their jobs. So, the CPC tried to keep growth high by flooding the country with cheap, cheap, cheap capital (loans!), and giving it to their industries, to keep them growing and growing in the short-term. The problem is that those industries really had no new opportunities to De-Fuck China, and gain revenue, to pay back those loans. And now it's the long-term, and all those loans are coming due.
This is one of the nice things you can do in a state-run economy. When Wall Street flooded homebuyers with cheap capital in 2006-7, it was the actions of a few greedy bankers, and so people pointed the fingers at them and also maybe said "Washington, tighten your fucking laws please". It was a "rein our bankers in" thing. When China flooded its manufacturers with cheap capital, *now*, it was a matter of government policy. People will say - if they can - "Beijing, you fucked us over. You did this."
Also, housing is important, but not what America's economy was based on. Our economy got fucked mostly because investments (by people, pension funds, corporations with no real business investing, like GE) in housing got fucked. China's economy is built on manufacturing, the sector that now cannot pay its denbts. What will you do, if all the factories go bankrupt?
