In Yemen, 65% of the population is aged under 25 years of age – and the unemployment rate is around 30%. I believe that in Tunisia the revolution was partly caused by the number of educated young men that didn’t have jobs but did have mobile phones – and access to social media. So where else in the world do you have lots of young men with phones and no prospect of work? The US might be one answer, the UK another, but I think we need to factor in some other factors (more on these another time).

Interestingly, while China doesn’t fit the formula now, it might if there was an external event that caused its export orientated economy to slow down and its young men to become unemployed.
