TOPIC: ARGUMENT17 - The following appeared in a letter to the editor of the Walnut Grove town newspaper.
"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ-which, like ABC, currently has a fleet of 20 trucks-has ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."

The argument presented above seems relatively sound for recommending that
the town of Walnut Grove should continue contracting with EZ Disposal which is supior to ABC Waste, based on that evidence that the frequency of collecting trash by EZ is higher than that of ABC, that EZ has order an additional fleet of 20 trucks and that a recent survey shows the satisfaction of EZ. However, after a close scrutiny, I find several flaws in this letter.
In the first place, this letter makes an unwarranted assumption that higher frequency means better service. However, it is not the case at all under many circumstances. It might be the case that the enviroment condition in Walnut Grove town might be well kept, therefore, once a week might be enough for the trash to be collected, and EZ's twice collection might be due to their low efficiency of work. Therefore, when considering this facet it is questionable to choose EZ Disposal rather than ABC Waste with a possible higher efficiency.
In the second place, the author of this letter fails to consider that there is a possibility that the increased trucks would be used in other town not in Walnut Grove region. If it is, then, it is unfair for the citizens in the area of Walnut Grove to pay for that money. Because they would not benefit from the additional trucks. Hence, without ruling out such possiblity, the author's claim of choosing EZ would be detrimental to the habitants in that region.
Last but not least, even if two times of collection would be needed and the new trucks would be used for the benefit of Walnut Grove town, the survey result of the percentage of satisfaction remains questionable. The author fails to provide any information about how many respondents are surveyed, whether it is only 10 out of 1000 citizens? Moreover, no evidence is given about how these people surveyed selected. Were they randomly selected from all the habitants? Maybe those who are unsatisfied with EZ are not contained in the study. The number of people surveyed and the way the survey conducted are important to validate the survey results.
In sum, based on the discusses above, the letter lends little credible support to the recommendation of choosing EZ Disposal as compared with ABC Waste. Unless information about the efficiency of both trash company, the usage of the addition trucks and the validation of the survey is provided, this rcommendation would not be that convincing as it stands. To better evaluate EZ Disposal, the author of the letter could ask someone having experience with both EZ and ABC for detailed suggestion. |
