  Political theorists typically take for granted that states must treat all of their constituents as free and equal, so it is no wonder that so many are attracted to Walzer’s analysis of guest workers. (And it should be noted that countries like Germany have since dramatically revised their guest worker policies, so that they are now much more in accord with Walzer’s recommendations.) Still, at least two big questions present themselves. First, even if we assume that Walzer is correct that long-term visitors like those employed in Western European countries must eventually be given the opportunity to become citizens, it does not follow that all guest workers must be treated as equal citizens. What if Walzer were to spend a year as a Visiting Professor at the Sorbonne, for example? Would this arrangement be morally impermissible if the offer did not give Walzer full voting rights in France for that year? Presumably not. If so, then there are interesting and difficult questions about how long and under what conditions one can work in a foreign country without the standard rights and privileges of equal citizenship before one becomes objectionably treated as a political subordinate.
