In management, the first concern of the company is the happiness of people who are connected with it. If the people do not feel happy and cannot be made happy, that company does not deserve to exist... The first order of business is to let the employees have adequate income. Their humanity must be respected, and they must be given an opportunity to enjoy their work and lead a happy life.
