"Courtesy is rapidly disappearing from everyday interactions, and as a result, we are all the poorer for it."

argument 10
The following appeared in the opinion column of a financial magazine.
"On average, middle-aged consumers devote 39 percent of their retail expenditure to department store products and services, while for younger consumers the average is only 25 percent. Since the number of middle-aged people will increase dramatically within the next decade, department stores can expect retail sales to increase significantly during that period. Furthermore, to take advantage of the trend, these stores should begin to replace some of those products intended to attract the younger consumer with products intended to attract the middle-aged consumers."

“礼貌正在从每日的交流中迅速消失。作为结果，我们都缺乏它。”

argument 10.       
财经杂志的意见栏：
"一般而言，中年消费者的零售消费额的39％用于专卖店的商品何服务。而在年轻一些的消费者中这一比例仅有25％。由于中年消费者的数量在下一10年中将大幅增长，专卖店可以预期他们的销售额会有大幅增长。进一步，为利用这一趋势，这些店应该开始将一些吸引年轻消费者的商品替换为吸引中年消费者的商品。"

1,ungrounded assumption: an increase in the number of the middle-aged will automatically translate into the increase in the sales of department stores.

2, all things are equal.

3, ungrounded assumption: the yonger consumers cannot constitute the major consumers in the department store.

any other fallacies?
