Foreigners currently make up at least 10% of Ireland's population (4.5 million), but in Dublin the percentage is even higher. Moore Street seems to be the privileged observatory to see the Dublin of the future. Here, in particular, it is the Poles who are in charge. Their arrival is the result of a brave and unconventional choice made by the Irish government in 2004 to open its labour market to citizens of the eight Eastern European countries that at that time joined the E.U. Now, however, with Ireland crushed by the economic crisis and saved by a bailout, there is the risk that not only the Poles will pack their bags and return home.
