These Fortune forecasts of aspects of life to come around the bend of the decade do not indicate that the seventies will economically swing any more than the sixties: the 4% Gross National Product growth (at best) is not staggering; population has been held in check here and the birth rate has been falling off steadily: the automobile manufacturers are more sanguine of gains than the Fortune market researchers; home goods need new products to keep pace and only housing should have a real boom, a long time delayed. As for fashion, we looked for some intiMIDIating innovations but this essay is angled on what has already attended the youthquake. . . . Well based and well analyzed, as usual, but hard to project a consumer market for this which the magazine has not already absorbed.
