What's changed for Tunisians since the Arab Spring?

On December 17th 2010, a man named Mohammed Bouazizi set off a chain of events that led to the Arab Spring. A graduate, Bouazizi struggled to find a job worthy of his qualifications and started selling fresh produce on the street. Harassed by police, he set himself on fire in protest. His death triggered a wave of protests against the regime of President Ben Ali, which soon spread to neighbouring countries. But two years on, the problems that led to the unrest - such as unemployment - remain.
