Woj, there have been plenty of incidents in Ireland alone where Polish (and other Eastern European) workers have raised very serious complaints about their working conditions and in particular the inferiority of those conditions as compared to Irish workers. There are also plenty of them involved in broader labour rights organising. It's pure fantasy on your part to suggest that they're all just so happy with their EU wages, they don't even notice anything else amiss.

I suppose it is, when you're not one of them.
