This book sheds light on the risk of an academic bubble, analogous to a securities bubble in the economy, with a primary focus on vocational education. It is often said that education is the key to success - best evidenced by university degrees and academic titles. But what if the chosen educational path towards higher education turns out to be a dead end? What if formal educational qualifications, like money or securities, become virtually worthless overnight? Based on the theory of Kondratieff cycles, it describes how bubbles can form in the economy and why the concepts of education and economy are more closely intertwined than often assumed. It also addresses societal issues that accompany this bubble formation and the devaluation of educational qualifications, as well as the related questions.
