最大的问题是我们能否摆脱经济过山车，回归强劲增长而不靠债务推动的过度消费（如2008年前的美国 ） 、 过度投资（如中国）和政府支出过度扩张（至今依然是欧洲一些国家的问题 ） 。
The biggest question is whether we can get off the economic roller coaster and return to robust global growth without debt-fueled overconsumption (as seen in the pre-2008 US), overinvestment (as in China), and overexpansion of government spending (still an issue in some parts of Europe).
