Yes they are. However, we don't have a homeless nor an addiction problem like exists here in North America or even some parts of Europe. The mentally ill will often have family members or known individuals that will take care of them. Seeing homeless people camping in parks is SUPER rare and I'd say actually unexistant. To us, one of the most shocking aspects of American society is actually homelessness and how most don't seem to care about others. In our culture even total strangers find a way to be housed by someone in case they loose their home.
