I mean, as long as they're built well there will come a point that they're repurposed. Seems like a lot of them are well maintained, but a lot of them aren't (not necessarily endorsing the rest of that channel, don't really know much about it this is just a good example of the pop up real estate stuff China is doing).

China absolutely has some serious problems with inequality and some massive contradictions that need to be reconciled. They're on a good path with the huge investment in fighting poverty and building an alternative to the IMF for developing production in Africa, but they're not perfect. I think real estate speculation is one place where China really falls flat.
