Take Syria for example, after initial protests government raised salaries but lack of food wasn't what brought people together in the first place so protests grew into full revolution then an armed rebellion continued till now.
Look at Egypt, now it's way way worse than Mubarak's era. Yet they are not revolting for a reason.
In Algeria, they felt humiliated by having such a disabled president that can't even speak.
Think about Bahrain too, a rich gulf state that witnessed massive protests.
Also not taking into account that people of different sectors of the societies took part in different parts of the revolutions, protesting or fighting, whether poor barely make a living or rich got back from overseas to make history for its home country, is very insulting to their sacrifices, and results in a very shallow and simplified view of how Arabs think.
