Earlier quoted context omitted.
I think you missed the poster's obvious sarcasm. As for "China's economy has plenty of growth left in it": the issue is not the amount of growth, but the source and quality of the growth.
Sure, 'twas obvious sarcasm, my bad. But there are good reasons for China's economy to grow sustainably for some time yet (emerging middle class, manufacturing going more high-tech, etc). They have major structural problems too, but it's not all doom-and-gloom like Japan is/was.
Of course there are good reasons for it to grow. Hopefully, the unwise choices driving the property bubble won't squelch it.
But the bubble will pop.
