Most of what you are writing was true, like a year ago. Never forget that China develops at internet speeds. Here's an update as far as I can tell.
Credit-cards are very much existent right now, to the extent that I know people who got into nasty trouble with them. That's a thing of the last year or so.
Overall credit is a lot easier to get now, which makes the real estate market feel pretty bubbly, but there does seem to be a never-ending demand for new property. First reason is that in the cities you don't marry without an appartment. Second reason is that people are still moving in from the countryside & those that get lucky end up in a position to buy after a few years.
I thought Starbucks was 'out' and the Coffee Bean was 'in' last time I visited. Same story that happened with McDonalds a few years ago: a western brand gets popular just because it is 'new', then people realize that they are eating/drinking crap & come up with their own alternative. Ever noticed how western fast-food joints sinicize (is that a word) their menus? That's not about concessions to the chinese tastes, it's about survival.
You're totally right on the copycat factor though & I actually think that's a great asset of chinese entrepreneurialism. It's a cut-throat world with lots of competition & they know how to stack the cards to their benefit. And why should they not? Unlike the western world they have a massive internal market to develop and cherry-picking 'the best from the west', then copying is a very valid strategy.
There's lots of cash to be made in luxury products I think. Just like the Japanese developed a taste for expensive watches 2 decades ago, I see the same happening in China. Over here in Switzerland jewellers / watchmakers are now openly catering to the asian market. I was in Luzern last weekend and just for fun started looking at the customers in the watch shops: almost all asian faces. And that makes sense, because most of my Chinese relatives will smuggle back a multiple of the allowed $10K worth of watches/jewellery every single time they visit europe. And those people are by no means 'fuck-you' rich in the Chinese sense of the word.
