it's a really good new that Polish people are more and more happy with their living conditions.
Better education means more opportunities at home as well as abroad, even if one doesn't necessarily choose a career they went to school for. Better job, more money less material and financial troubles.
Poles have always been easy going, friendly and open people it's just that during communist times even the basic necessities like a home of their own, good paying job later even supply of food were hard to come by making people miserable and worried all the time.
