In 1994, photojournalist Peter Menzel and his wife, writer Faith d’Aluisio, published a book called Material World: A Global Family Portrait. Almost going bankrupt for their project, they showed us a “curious evidence of the material world we live in”. Joined by sixteen of the world’s foremost photographers, they traveled to thirty countries to live for a week with families that represented the average middle class for that State. At the end of each visit, the photographers took a picture of the families outside their home, surrounded by all their possessions. Their photographies reveal what is pointless to express in words and their question remains of interest: Can all six billion of us have all the things we want?
