Yes and no. I am not sure which city or when you went, but I have seen major changes in most of the cities. Yes, there are, what we would call slums, and then there are the high rise apartments. What is interesting is the rising middle class in China. As such, things are improving. The living conditions we see today in China can be described what the living conditions in the early 20th century where running water was not available everywhere. The main problem with the housing, at least from my perspective, is there is no resale value. Once you buy the apartment, you pretty much stay there for life. Also, China tends to build up and not out as does the US, most notaly in the SE, South, SW, and West parts of the country. It is different and as such you cannot make a comparison.
