The well known columnist-author-lawyer enjoys a holiday of prognosis instead of diagnosis in a statistic-slinging present day proof to the preview of America in 1976. He suggests that we won't use the atom for warfare, that new energies will give us more free time, and that we will become more active creatively, learning to live life for itself and through leisure. His concerns include the burgeoning of prosperity and population; the supply of minerals and food (here comes that chemical vegetable garden for the city dweller); a general education plan -- a GE bill to succeed the GI bill; the problem of bigness in business and government (we shall have a minister of free enterprise to help the smaller firms). The choice of 1976 is generous to both author and audience, allowing the one to employ his armful of statistics in forecasting and the other to Judge his success when 1976 rolls around. Mr. Ernst is admittedly an optimist, but whether a ""cockeyed optimist"" or not remains to be seen!
