In Mexico, in the beginning of the 21st century, young adults face big challenges to be able to access to the level of higher education and to good jobs. People who have not had the opportunity to study are devoid of a proper instruction to exercise an economic formal activity. When they interrupt their studies they will lack the knowledge to perform professional activities. Even when they have concluded his university studies, not many will have a vocational training adapted to the requirements of the new society. In this context of social exclusion we ask the following question: How can we contribute to the integral preparation of young adults to help them obtain a better life and work?. This goal should consider teaching ethical contents, which can generate social action, based in scientific knowledge and respect for fundamental rights. To answer this question, we will present a comparative analysis of the ethical values of social scientists in five fields of knowledge: Administration, Communication, Law, Education and Sociology in five open education systems of public and private universities.
