The factor of footlooseness is, therefore, the more serious, the bigger the country. Its destructive effects can be traced both in the rich and poor countries. In the rich countries such as the United States of America, it produces, as already mentioned, ‘megalopolis’. It also produces a rapidly increasing and ever more intractable problem of ‘drop-outs’, of people, who, having become footloose, cannot find a place anywhere in society.
