Abstract
I looked for a robust yet flexible modus vivendi for a decent society of migrants and citizens. My proposition for a modus vivendi is on two levels: political and residential. On the political level, I propose the implementation of a new form of citizenry within the new limited cosmopolitan space. On the residential level, I propose that governments of nation states, as much as possible, adopt the working procedures of the municipalities of global cities where migration is dense. Such procedures may pave the way to decently accommodate social and economic networks for the survival and even the flourishing of the legal and illegal residents of global cities in spite of the current reduced and rigid concept of citizenry. I, then, conclude that, just like at the genesis of home computers, during which children taught their parents how to master this new ghost that intruded their private space, municipalities of global cities have to teach their governments how to deal with the problem of migration that intrude the public space. As a result of this interaction, governments may legislate more flexible laws of citizenry in the newly transformed public space.
