Its a fact that Polish ppl do not integrate and this will push them further apart from the native community.
No, it is
not a "fact" that Polish people
do not integrate; we have been here for over 60 years (there were nearly 250000 of us befure Poland entered the EU, but few Britlish people even realised this), but it is only since 2004 that there has been a large influx of new Poles.
Previous generations of Polish immigrants integrated so well, that we were barely noticeable. I was brought up in a bilingual family, and have had professional and social contact with many thousands of Poles over the years, in half a dozen UK cities and abroad, so I know what I'm talking about.
Currently, the community is much more noticable, due to increased numbers, but
a minority have no interest in integration - and these tend to be the thick ones who would be unemployable in Poland, never mind in the UK, and who struggled with
Matura in Poland, so they are hardly going to become fluent in English very easily.
The days of mostly intelligent, highly educated immigrants "escaping oppression" in Poland are long gone, and recent immigrants represent a much wider cross-section of PL society - which naturally means a lot more "bad" ones have come over recently as well. As a result, many can't and don't assimilate, or are unlikely to. But this is NOT the majority of Poles.
