It is weird because in the time of need we seem to do very well as a team; when things are good, we revert to bickering and poor organization.
I know you are refering to Polish people but I think this applies to all humans.
Being an immigrant is tough in so many ways and it isn't for everyone. As the economy is not strong one can predict backlash against the new members of society. One one hand they are welcome, on the other they are resented. In any case they should be careful and behave well. They lack seniority.
I agree and I think most immigrants don't immigrate out of real choice.
The Jews were being persecuted throughout Europe and probably other places, when Poland took them in.
The Polish king at the time wanted their business and banking skills, I believe.
While the Poles have been invited to Ireland and some other E.U countries.
Polish people had the chance to get work and in many cases earn more than they did here in Poland.
While Ireland needed the work force.
i don't know if i am being too, black and white about this, it is a generalisation.
My point is, most people would prefer to stay at home, given the option.
