What is the effect of Economics on the Egyptian Demonstration?

This is a graphical context of middle 60% PPP annual household income for several European, Middle Eastern and Asian countries.   Those countries either involved in direct war with the United States, or that have recent uprising and demonstrations have their annual incomes  boxed in red.

While the issues are so very much more complex than just economics, share of world income  partially explain demonstrations in Tunisia, Jordan, Yemen and much more vigorously, Egypt.  Compared to others in the region that have either created diverse economies like Turkey, or whose populace have benefited from oil revenues like Saudi Arabia, these countries average incomes have lagged well behind, and their citizens sense little say in their futures.

Compared to India and China, they fare better financially, if we look statically at their current purchasing power. However, the latter countries’ citizens look forward to growth through active private and public investment where the former do not.
