Thousands of protesters march through the streets of Madrid.Dubbed the "Indignants", they are calling for fundamental changes to Spain's political and economic system. It is a cry that comes as the country struggles to deal with mounting public debt and an unemployment rate over 20 percent."This system isn't working. The working class and the poor classes are paying the price of the disasters caused by the bankers and speculators. The people we voted for constitutionally are incapable of halting the speculation of the markets."
