@Dutchess_III I understand your wanting to understand “Why do some people seem to want to be a student forever?” But the thing is, your details contradict your question, and when you clarify, you seem to walk back what you’ve said already.
So, here’s my take on it:
“They get their Bachelors. Instead of trying to land a job with that”
This assumes that everyone should be content to get a Bachelor’s degree at most. As others have said, some of us want more than that – partly out of desire (for our own growth and development as human beings, and because we want to know more), partly out of a feeling of service (because we know we have more to offer than what we could do with a Bachelor’s degree).
“and continuing their education around their job,”
I honestly don’t know that many fields where this is possible. Not in the sciences. Not in many of the arts. Perhaps in the more “technical skills” fields, like accounting. But I would not guess that most graduate students are able to do this, partly because the workload is too heavy, and partly because some fields forbid it outright. I should add that I worked more than full time hours for a company during my Bachelor’s degree, but I had to quit the year before graduating, because otherwise I would not qualify for graduate scholarships. The major funding bodies would not give scholarships to people who were not full-time undergraduate students.
“they choose to go for their Masters. Then their Doctorate.”
This makes it sound like a Masters is the same as a Bachelor’s, just longer. And that a doctorate is the same as the others, just longer. But this is not true. A Master’s degree is qualitatively different from both a Bachelor’s and a doctorate. A doctorate is qualitatively different from both a Bachelor’s and a Master’s. To drastically oversimplify it, in a Bachelor’s degree, you are taught. In a Master’s degree, you learn how to learn. In a doctorate, you learn how to teach. It’s not simply a matter of filling up a vessel with knowledge. It’s learning how to recognize gaps in humanity’s knowledge, and deciding which of those gaps need to be filled and how.
“They can spend decades on this endeavor, never actually working, always being a student.”
If someone is aiming for a doctorate, yes, it will take at least a decade to reach that. They do this in the full expectation that they will get a job afterward. Decades? No, probably not.
The other two things about your question that I want to address are these: (1) A person can be a student, and be working very, very, very hard all the time. They can also be making a living from their work as a student, through scholarships, fellowships, TAships, RAships, and through stipends from their advisors. And yes, also student loans. They may or may not be paid to be a student, but at the graduate level, odds are someone is paying them – though usually not well. This is an investment on the student’s part, in the hope that they will have a good starting salary in their field when they finish. Some of your later comments seem to indicate that work is only work if it’s being compensated by a corporation that is making profit (as I read it). I don’t know where this assumption comes from. It’s not one that anyone in academia shares.
(2) There are people who want to be “in school forever”, whether because they value the process of scholarship more than any other kind of experience, or because they are hiding from different kinds of experience. Some of them are hiding from the economy right now – it looks better on a CV to say “I was in school for 4 years” than it does to say “I couldn’t find a job for 4 years”. I think you are trying to say that your neighbour is like this. But in my experience, this doesn’t apply to the majority of university students, by a longshot. This is why your generalizations are meeting with such resistance and disapproval. If you limit your question to why your neighbour is like this, and give more information about his individual situation, it might be easier to guess (1) whether it is actually so and (2) why he makes that choice.
But as you’ve written your question, details, and follow-up comments, it actually sounds instead as if you are attacking those of us who are pursuing advanced degrees. I am a doctoral candidate. I have been in school for almost the past decade. I do not plan to be “in school forever” and I not only plan to contribute to society once I have a stable job, I am contributing right now, by doing and publishing research, and by teaching undergraduates. I’m just not getting paid very much to do those things.
