Unfortunate, but many jobs are gone and will never come back.
-Many jobs have gone to less-developed countries where costs are lower.
-Technical advances, esp. automation in factories, have eliminated many jobs.
-New ways of doing business, esp. in retailing, are cutting the number of stores on the street and the employees who work in them.
Shopping on line is already strong- the number of catalogues one receives in the mail increases evry month. Why leave the house to shop when the 'shop' will come to you?
-Advances in the dissemination of information are cutting publishing and library services, and changing teaching methods in schools.
This is only beginning, but in the next ten years the job situation in these fields will be greatly changed.

The upheavel in employment is world-wide. To avoid falling behind, strong control is necessary; this is lacking in the West at this time.
