This article presents the results of a study conducted among students in Education Sciences in France and Sweden on their concerns about social justice. Starting from an educational device promoting the sharing of their experiences and knowledge on the issue of street people in Europe, particularly the Roma, the text shows these students’ perceptions of these populations, who can be qualified as second-class citizens. The students’ comments reveal the degree to which street people in general and the Roma communities in particular are considered as second-class citizens. Indeed, they are people not living in the same conditions as other citizens, which makes it difficult to exercise their rights and duties as citizens. Moreover, school is not the forum in which students and parents from the Roma community can enjoy a form of equality, justice, freedom, or possibility of social promotion. It is, on the contrary, the place where they risk all forms of violence, suffering and discrimination related to their specific community of belonging.
