"Throughout the last two decades, those who earned graduate degrees found it very difficult to get jobs teaching their academic specialties at the college level. Those with graduate degrees from Waymarsh University had an especially hard time finding such jobs. But better times are coming in the next decade for all academic job seekers, including those from Waymarsh. Demographic trends indicate that an increasing number of people will be reaching college age over the next 10 years; consequently, we can expect that the job market will improve dramatically for people seeking college-level teaching positions in their fields."

The author claims that since the number of people who will go to college will increase, the jobs search for college teachers would be easier in the above passage. The argument is indeed flawed as the author overlooked the fundamental principle of supply and demand. Furthermore, reasons why the graduates from Waymarsh having a hard time finding jobs are not addressed, making it difficult to expect they will also have an easier time finding jobs in the next 10 years.

The primary flaw of the author's arguments is the lack of consideration of the both the supply and the demand in the job market. It might be true that the people attending college over the next 10 years will increase but if the number of the teachers available will also follow this trend, the overall market will still be the same in the future as in now. In the extreme case, once this trend is known to the students choosing their major in college, they might choose the teaching career because of the good employment prospects. This will actually burden the supply even more and an alternative conclusion would be reached.

Secondly, the author mentions the difficulties of graduates from Waymarch entering the job market. There could be a number of reasons for this. For example, the reputation of the Waymarch university is not as renowned as the other universities and therefore the graduates are perceived not as attractive as other graduates. If this is the case, then even when the demand for teacher increases in the future, it's difficult to draw the analogy that the same could be applied for graduates from Waymarch.

Although the author presents some bases for his arguments, he can significantly improve them by incorporating the following. Through some more research on the prospects of people choosing teaching as their future career, the author can provide more substantial evidence about the supply of the teachers and strengthen his conclusion of better job market. Moreover, adding more facts about the graduates from the Waymarch university and perhaps how the university is improving its courses and providing more teaching resources, the analogy of good job prospects even for them can be justified.
