Raffaele Petralla, a documentary photographer...was in Bangladesh to document the brick factories that cluster around Dhaka...Near each factory there was the village of the workers...The houses were very bad -- only 1.5 meters high, so you can't even stand up inside -- and without electricity...all those living in the workers' community had come from other parts of Bangladesh, mostly tiny rural villages far from big cities. They were lured by the promise of decent housing and a wage that would sustain them even in the months when the factories are closed...With wages kept miserably low, the families need every salary they can get just to survive -- and this means children as young as 6 work long hours, too, Petralla said. Their pay is the same as that for adults, based on the number of bricks transported daily in woven baskets loaded onto their heads.
