University degree - Is it a token of Employment?

The world is changing. Human culture started to develop about 315,000 years ago. The language was developed about 50000 years ago. Even homo sapiens needed skills. They must be recruited based on hunting-gathering skills. Graffiti in caves were made to teach a future generation how to survive and become the fittest. The graffiti became language and writing on walls became classrooms. They did not have a college degree. In the modern era of industrialization, knowledge became complex. And people who know made it scary by cartelizing that in name of degrees. Freely available knowledge became a money-making machine. Following that those who were in scarcity of knowledge made degrees mandatory to get a job. Skills were not a priority for such businessmen. In the future, when Mars is about to be colonized, people with skills will get tickets first than the people holding degrees. Just my point of view. This book calls for a priority shift from getting a token for the job to acquiring those skills which make one employable & stay in the job for a long. Employers too are demanding skilled people. The degree is just an assurance of what you have learned when it was time for you to learn.
