I'm going to save the "I told ya so." At many times we forget that 2 + 2 = 4. No matter how many people say the solution is 5, their ignorance (or deception) can't stand in the face of current events.
The violence in Egypt and Tunisia along with protests in Albania, Jordan, and Albania are such current events.
Quantitative Easing (QE) has pushed global food prices so high that people in fragile economies are going hungry. These people aren't protesting and turning violent because of a political or religious ideology--they are out of food. This creates the kind of desperation that inevitably leads to violence, and even revolution.
