Talk to the classmates who have seen it about the migrant workers in the movie.
Glen is an old failed Irish young man, in his own words, a hoover fixer sucker guy; he sings and sings on the street for some money, and goes home to help his dad fix the vacuum cleaner.
Marketa, an out-of-towner from the Czech Republic, lived by selling flowers and sometimes helping out as a cleaner.
Marketa is a migrant worker to Glen, as you can tell from his defensiveness towards her at the beginning of the movie; Glen looks at Marketa the same way he looks at the punk who stole his money at the beginning.
And Marketa has an idiot's husband who stayed in the Czech Republic and came to Dublin by himself; Glen's girlfriend also went to London alone, living in Chiswick, not a place where rich people live. By the end of the film, Marketa's husband finally decides to come to Dublin from the Czech Republic to find her; and Glen finally decides to leave Dublin to go to London to find his girlfriend.
Glen is to the fake guys in London what Marketa is to the peasants of Dublin, a migrant worker.
I hope to take this film to educate the majority of Dubliners, Londoners, Shanghainese, and Beijingers: You are also migrant workers, please don't wear tinted glasses to look at your compatriots from other places around you.
