Recent social changes in the country of Spiessa lead the author to predict a continued surge in growth of that country’s restaurant industry. Rising personal incomes, additional leisure time, an increase in single-person households, and greater interest in gourmet food are cited as the main reasons for this optimistic outlook. All of these factors are indeed relevant to growth in the restaurant industry; so the prediction appears reasonable on its face. However, three questionable assumptions operative in this argument bear close examination.
The first dubious assumption is that the supply of restaurants in Spiessa will continue to grow at the same rate as in the recent past.
最初の怪しげな仮定は、Spiessaでのレストランの供給量が、昨今と同じ速度で成長し続ける、という点だ。
最初の疑わしい仮説はSpiessaのレストランの供給はここしばらくの成長と同じ成長を続けていくということである。
その一は、Spiessa地方のレストランの供給の成長は過去と同じ成長率で行われていくということである。
