The Polish that come to the UK are more educated than the British.
I'm sure some of them are. I'm also sure that some of them aren't.
Never generalize, it just shows your ignorance.
I'm Polish and I love Poland but if Polish people were so much more educated than other nations, English being the example given here, what is with the mass exodus to other nations, England again being a prime example? Obviously, the English can't be that uneducated that people are immigrating to their region by the masses. It would be difficult to run a nation that is still one of the richest in the world if there would be so many 'dumb' people.
That being said, my mom went through the Masters program in Poland and was able to get a teaching job in Canada without a problem. She also continually get job offers to work for the board to work on the math curriculum (they're constantly changing the curriculum after every provincial election, because apparently the have nothing better to do) even though she mastered in history and not math. But then, I also know people that went through the same system as my mom and struggle to get a decent job. It also depends on the person. Not everyone is good at the same thing.
I used to sit in class looking out of a window somewhere in Britain.
Then the bloke who is now my flatmate spent his schooldays looking out of a window somewhere in Poland for his education.
Sounds like Canada too.
