One needs to disaggregate data to get a full picture of what happens in China due to the rapid evolution of things. Forty years ago very few people went to college. It's a big bulge of population that are not going to upgrade their skills (mostly retired but things like learning to drive or using the popular apps are still difficult for most who have not already learned). They are also very used to hardship and will consume little even if they come into unexpected wealth (say from housing). The demographic shift will not play out as everywhere else.
“Elderly Chinese people are different from elderly people elsewhere because they’re hardier” doesn’t feel like the extraordinary proof the earlier extraordinary claims required. Are they that different from people in other middle income countries like Thailand?
The point is that old people in US and specially Europe expect to maintain their life standards, which are quite high. That's difficult in the middle of a demographic downturn. But that's not the case for elderly people in China. Even if their numbers do increase over time, the productivity of younger generations is so large compared to them, that they can effectively be supported with little problems for the Chinese government. So in a sense China is lucky that their economic growth is occurring exactly at the point where the demographic change is starting to happen.
To be clear, which of the newly-industrialized countries classically described as being in the middle income trap do you think that's not true of? Like is China going to be different from Mexico here because abuelas are demanding a high-standard of living?
The word "middle class trap" only makes sense for China based on FX rate. Rich Chinese will continue to diversify if not outright emigrate while the middle class is trapped by necessity. Meanwhile the savings/investment rate is so high that the Chinese middle class will enjoy things that middle classes in few other countries have, once normalized for population density. Right now they already lead in industrial robots per worker (behind only South Korea and Singapore). They will lead in service robots per capita one day as well.
For example, Chinese coffee chains are beating Starbucks in China:
"The pace of growth of domestic coffee chains has been impressive in the past year. Luckin’s performance has been especially strong. It has proved sceptics, who once saw its ultra-cheap coffee prices and high costs as a flawed business model, wrong this year. Luckin Coffee’s operating margin hit 15.3 per cent in the latest quarter as net revenues rose more than 40 per cent to $1.5bn, adding to annual sales that nearly doubled last year. It opened 1,400 new stores in the latest quarter, bringing its total to 21,300. Meanwhile, signs of the pressure are showing with same-store sales at Starbucks down 14 per cent in China last quarter."
"Automation, a rapidly growing trend in the local coffee chain industry, is helping margins during a time when costs are rising, especially delivery, sales and marketing expenses. Cotti, which has grown rapidly since it was founded in 2022, is pushing out coffee-making robots. Luckin has fully automated pour-over coffee machines. Luckin’s coffee robots and unmanned coffee shops were key to maintaining growth during the pandemic."

And you would be hard pressed to find anyone middle aged or older that actually drinks any coffee.
