You are hugely mistaken. Many people who live in those cities are on average richer than those who live in the San Francisco Bay Area. Now I am not talking about China as a whole (as some don't have access to free running water) but for the ones that can afford it.... they certainly CAN afford Apple products.
I am more surprised at the fact that there isn't an Apple store in Hong Kong yet (7 million people in a place smaller than San Francisco, and a place where both Westerners and Easterners meet)
lack of running water is certainly true, I was shocked while visiting my relatives that there were still places with no running water, and ironically, lack of any sanitary standards in a hospital in rural china. In my student job, I can make more in a day than most of my relatives in a week.
Another thing many don't consider is the chinese attitude of "what does it NOT do?" With that mindset, most chinese ppl will be quite dismissive of apple products in general, especially the fact that many of them still remember the apple of old, and continue to blow off the apple of now thinking that not much has changed since the apple of old. It took a lot of convincing on my part to get my cousin to get a macbook pro (which she fell completely in love with after my dad brought it to her, and saved her quite a few hundred USD by having me purchase it in the US)
sure, through overseas relatives in the US. Relatives go buy on amazon.com, or in tax free states and schlep them over on their next visit.Can the chinese afford Apples ridiculously priced products?
