I typically do not respond to posts about China partly, because I simply do not believe I know enough about it to comment appropriately. Still, what I do know is that accurate information about China in general is a lot harder to obtain that information about US. From get go this means that any discussion about demographics, real estate or banking is more speculative than anything else. Worse, it is hard to rely on anecdata, because of how large China's population is and how ( as I learned recently ) un-united China's population is ( when compared to US ). Those two factors alone should make one hesitate with offering any major predictions on its trajectory.

I am not automatically saying you are wrong, but with exception of real estate, there is little I can find where somewhat verifiable data seem to support it.
