The problem is that stereotypes matter a hell of a lot when it comes to someone's future. Look at Poland - we Brits know that Oxford/Cambridge entry depends on a lot more than just grades, especially if your father is a member of the old boys club. But Poles? They don't know this - they just know that the degree is from a world class university. They've got no idea that someone who blagged his way into Cambridge and left with a 3rd class degree is really just a waster - they've got a paper!
Likewise, someone from Sweden is going to see that no Polish university is ranked higher than 350 in the world - and they've going to deduce from this that Polish education sucks.
I have never studied in Poland (only in Sweden), but from what I've been told cheating seems far more common in Poland. It's really hard to get away with cheating at Swedish universities and the punishments are harsh so few are willing to risk it.
Pretty much bang on. Cheating in Poland is part of the system - and unfortunately, people are then surprised that people cheat and lie in business.
The Polish system isn't all bad - the problem is that there's a vast amount of people who owe their position more to nepotism than to talent - and these same people make dreadful lecturers.
This is, after all, the system where a good businessman isn't welcome to teach, but some dreadful PhD is. I leave it to you to decide what value a PhD in Business might have.
