In his well-publicized book The Mystery of Capital (2000), Hernando de Soto claims to have discovered the explanation for poverty in countries of the Third World and the former Soviet Communist bloc. He claims it is the inability of the poor people in these countries to convert their "dead capital" into live, functioning "capital" because of a "legal apartheid" their governments have created. When a businessperson says he is looking for some "capital" to invest or set up an enterprise, he has in mind a sum of money (funds), typically to be borrowed at interest. Some of the funds may be used to purchase or rent machinery or equipment, rent space for the enterprise, purchase raw materials, and pay for the services of workers. Some of the funds will also be kept on hand to pay incidental costs that the enterprise incurs or to provide change to customers before revenues start to flow in.
