NIJAR: After seven years living as an undocumented migrant in Spain, doing day jobs and staying in shanty towns, Moroccan Abdelmoujoud Erra hopes a mass amnesty launched by the leftist government may finally turn his fortunes around. “Without documents you work for five euros ($5.80) an hour. With documents, you work legally, with more money — maybe seven or eight euros an hour,” said Erra, 27, in the southern Spanish province of Almería. Undocumented migrants there gather at roundabouts hoping to be hired to pick fruit and vegetables in Europe’s largest concentration of greenhouses.
