AI：Governments should not be responsible for regulating businesses and other organizations. Instead, society would benefit if the organizations themselves assumed most of the responsibility for establishing and enforcing their own standards and regulations.
AA:The following appeared as part of an annual report sent to stockholders by Olympic Foods, a processor of frozen foods.
"Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits."
