This video says about itself:
We are the students of the University of Zagreb (Croatia). We are involved in a fight against the neoliberal policy of our government which includes the introduction and constant rising of college fees. Not so long ago, university education was free in Croatia. Now more than 50% of the students are paying their own tuitions. In May 2008, we took the streets and had our say about it. Come 5th of November [then, in 2008], we will do that again, united with the students of the world.
The fight has just begun!
