经济学在每个人看来都是不同的。一颗钻石，从正反两面去观察，得出的视觉印象是不同的。同一问题，看法也不一样，我无意反驳你，只是看问题角度不同。

楼主有气度

Interesting, if we look into 楼主's view, we find the the logic behind his view is quite arguable;

1) "阿拉伯世界，前途也是光明的。因为阿拉伯现在进行的是政治革命，虽然现在军事冲突和死人事件频发"--Is  he sure there is connect between 阿拉伯世界 with China in this context?

2) "中国有上千所大学，年毕业几百万大学生，这些人在社会上和工作岗位上为中国尽心尽力，推动了中国的各方面的发展" Is he sure "Quantity" will definitely end up with "Quality". Think from different angles, if those huge amount of graduates cannot have a good matching in the job market. What problems and society costs will be resulted? On the other hand, we cannot assume that human capital is fixed or limited to certain country/area. Does he know how many human capital lost from China to Western Countries every year?  How many top students would prefer working for multinational companies (MNC)? Why so many MNC target on Chinese top graduates every year. And even so countries (i.e. Singapore) have policy to attractive Chinese talent to work and even stay in their countries.

In fact, I share with his view that China should be better than ever-- but on condition that China can overcome the coming challenges. I think if China cannot develop its domestic markets, but simply reply doing export business on US and European markets. It will encounter problems maybe even more than opportunities.
