Because being a graduate is not the key to being wealthy? Majority of the richest people in the world did not even finish college, and the ones who did usually did not finish anything major neither. Education teaches you how to be a great worker, not how to be a great business owner, it doesn't teach you how to lead, it teaches you how to follow. That is why education exists, to give you a guaranteed path, and if you follow it, you will find a good decent job and live a mediocre life.
If you do not study though, you could technically be like Mark Zuckerberg, or you could be the homeless guy around the corner as well, who knows. People study, to have a certain minimum, but it doesn't give you a key to wealth at all, that's not even the purpose of it.
I think many people have misinterpreted the true meaning of education. Education is not to make someone rich, but education is a process for someone to expand or deepen their knowledge. It may be possible to become rich by pursuing higher education, but it is one of the thousands of paths available and I think it depends on the person.
I see many people who pursue higher education just for the degree, while their knowledge does not increase at all because they prefer to be outside the classroom when there are subjects/courses. But can we condemn them to never be rich? I don't think so. There are also those who are very diligent, but will that guarantee they will be rich? Not really. Once again I would say it depends on how hard the person works and dares to take risks.
Not literally rich in terms of money but it would be rich in terms of knowledge on which this is something that you would really be able to make use on your future endeavors. It is really just that wrong to have that kind of assumption that you would really be that getting rich already once you have finished studies. Just like on what said above that this is really just that the first step of your journey. Although it
wouldnt really be that easy but it doesnt mean that it would be impossible for someone to be able to achieve. It would really just that matter on how well you do make up those decisions and choices
in regarding on the things that you are dealing with, plus a little bit mix of luck on which this is something that relevant too.
This is why if you do have plans on making yourself that wealthy then it would be just that right that you would really be needing to take actions and be wise too.
If you do see that getting a job despite of a college graduate, then try other fields on which you could really be able to utilize your skills and knowledge.
Try and try until you succeed.
