Many factors to it. Family circumstances, financial situation all play a part. Also depends on what you are doing during the gap year, if you are travelling and exploring, that will give you exposure (but gotta have money first), if you are doing different kind of jobs, that will give you a better understanding of what you really want to focus on doing, or it could also be just spending some time doing volunteering, while waiting for a better job climate. No right or wrong answer. Just a matter of perspectives. Have a rational mind to weigh the pros and cons, as well as bear the consequences if there is any. But of course, if a person take a gap year just to do nothing and sleep at home, then I agree that's absolute nonsense. I think that if a person take a gap year, there must be a good reason to it.
