Everything is variable. We do not know if one thing can endure for a long time. There is a human tendency if we perform better if we enjoy a working while doing it. If one's work is also related to their passion, liking, hobbies, they do not consider that work as a burdensome anymore. Present kind of available job might be tempting in beginning but they do not provide satisfaction and one would like to give up at larger stage of life.

First of all, There is always a boom of few particular field in a zeitgeist, If every one strive to study that field in order to get a good job, then Obviously, there would be an imbalance between supply and demand. More college passout students and less number of jobs. This scenario would create a major issue at time. Furthermore, this imbalance would lead to unemployment which would further create an issue for college graduates.

Further, It is well proven that a person perform better when they do the job they like. That ways a person always enjoy their work. They never feel work as a burdensome and give their 100% to the work. They help to achieve impossible things which eventually helps to develop or invent new things. For example, If a student is a found of music and do like computer, and there is a demand of computer jobs in market. The student might learn some about computer, but he/she may never enjoy working with computer because that is not their forte. They will get satisfaction in music only. If someone is expert in a topic, there would not be any problem in that field. It is all about expertise now about the availability of jobs in market. Suppose a person join a job that he/she doesnt like, This would lead to a dissatisfaction and eventually cause to quit a job at later stage. Because that person would have only two ways, either continue with the work that one does not like or start a new job from beginning.

Another point, One can not predict that the demand of a particular field will always be same. For example, Now a days there is a demand of Machine learning, Analysis, etc because people want to invest only if they feel its safe to invest in such kind of field. While it was unimaginable few decades back. Any business works on a model which is start, peak and end. There is no particular profession which has same demand. ANd all the people choose the same job in the field and at later point, they came to know about the fact that their industry is going down, it would impact heavily on them, because at that time most of our habits entrenched tightly and we can not learn new things.

In a conclusion, College graduate should choose the job based on their hobbies, interest and expertise. There are many fields available and all fields are important. It is better to enjoy and perform better at your work than get stressed and feel bad at later stage in life. There is no surety that a filed will always have same demand. Only a true happiness can give a meaning of life.
