Look at the frame from iqbal. iqbal thinks constantly about how hard his life is, but he can't think of a way to be free. all the boys in the factory are debt slaves. none of them have a peshgi, which is what the debt is called, less than when they started to work for ghullah. after five years in the carpet factory it would become even worse for iqbal. which excerpt from the prologue of free the children reflects what is happening in this frame?
