Global citizenship is the apex of the humanistic ideal, and indeed the Christian one as well (for we are neither Jew nor Greek), but there is an inappropriate conflation of Generation Y/Millennial Nomadism with Global Citizenship.
The nomad fancies himself as a global resident, but he is actually a resident of nowhere. We are either residents of a place or of no place, but we cannot be residents of every place. We all must choose where to reside, and while many people have historically defaulted to where they were born, contemporary American youths default to the ‘glamourous’ cities they have idealized through various media since childhood.
We should choose where to reside because it is place that needs us the most rather than the place we feel we need to be in order to “be seen” or envied by others.
