"These pictures tell the story of the always present distance between people; the miles between families, the class distinctions among neighbors, the social divides keeping citizen and alien disassociated. The archetypal exodus story is one familiar to many in search of a better life. It is seldom that a people choose to migrate from a homeland rich in cultural and historical significance. Nevertheless, the human race has been on the move for some 70 millennia in search of a better livelihood. What separates modern migrations from those of the ancient past, though, is that they are no longer natural obstacles but conceptual ones keeping displaced people from opportunity. Hegemonic subscription to these socially constructed concepts of difference has proven fatal to many minorities world wide because of their creed or color. It is this perceived difference among us, and the value placed on difference, that has fueled ideologies of segregation and domination by church and state alike."
