Are they? I believe that everyone should, but I don't think that everyone is. If you think about it, some people are born with dispositions like mental conditions, physical problems, or medical conditions that could cause problems later in their lives. While this isn't the case for most people, it is these types of things that draw the fine line between equality and inequality.
Equality is the public recognition, effectively expressed in institutions and manners, of the principle that an equal degree of attention is due to the needs of all human beings. ~Simone Weil
