Make a list of products and services which are least satisfactory and have shown the least improvement over time. How many of these are produced by government? Do you agree or disagree with this statement by Milton Friedman: "Postal serive, elementary and secondary schooling, railroad passenger transport would surely be high on the list. Ask yourself which products are most satisfactory and have improved the most. Household appliances, television and radio sets, hi-fi equipment, computers and, we would add, supermarkets and shopping centers would surely come high on that list." Please answer in detail.
