So-called matching models are used in labor economics to explain how employers and employees find themselves in their labor markets. In efficient markets, the best candidates capture the best roles in the best employers. I thought that matching models can be considered not only from a labor market perspective, but overall matching in society. I thought of a couple of friends who could not find their place in our society. It does not mean they are not good; they are just not good for our society, which offers limited opportunities, and these limited opportunities require certain skills to capture.
