My point is that trajectory is more relevant to these discussions than current state of affairs. The quality of life of the average Chinese citizen (and more so the upper-middle class Chinese citizen) has increased DRAMATICALLY in the last 40 years. So when people talk about China's potential, they aren't talking about the situation in the next 5 or 10 years. They're talking about who is going exert massive international influence in the next 50 years. So you're right, most westerners aren't buying speculative property in Beijing (despite the fact that housing in central Beijing is nearly as expensive as New York City), but I'd wager there's a good chance of that changing in the next 50 years.
