The Real Reason the Middle East is Rioting

Tunisia's protests were the first, but after the protests in Egypt they have spread to Morocco, Jordan, Yemen, Algeria, Syria, Bahrain and Libya now spread to Turkey.
Turkey is the bridge between Middle East and Europe.

Is it the social unrest, or rise of fundamentalist Islamic religion,or is it rise against system, or is it provoked by western countries(developed) to gain the control?

I would love to know your opinions on this topic..
