You are also having people with a wrong understanding of the Chinese property crisis by trying to map it to the American Great Recession, when the two problems are very different.
For instance, Evergrande is a real estate developer, not a bank. Evergrande going broke is like if Toll Brothers went broke in the USA. It would be bad, but it isn't the end of the financial world.
Second, China doesn't have the mortgage industry that the USA does. China has mortgages, but a large part of the market is owned as investments. You also have to pay a lot more as a down payment compared to the USA. So, the exposure that the Chinese banking industry has to this is a lot less than what happened in the USA in 2007/8. However, this means that people are more at risk in losing money on their real estate.
Third, while housing in the USA is an investment that some people take, there are generally other ways Americans invest their money to save for retirement. In China, a greater percentage of the population saves for retirement by buying property. Given China's demographic issues, this can be a problem if a lot of retirees lose a significant part of their nest eggs.
Fourth, municipalities and provinces can't set their own taxes and the national government hasn't been giving them enough money to pay for services. Local revenue generation has been handled through real estate development. There has not been a plan released yet to handle the loss of revenue or dealing with municipal debt. National plans for real estate development are removing the profit incentive, so how does that impact local budgets?
Some of these points are covered in your article. However, even in this thread, the discussions seem to be trying to view China's property crisis through an American lens when the mechanics behind both are very different.
