If that is true then your social circles and experiences must have been extremely limited.
What utter nonsense. We just work and and interact with different types of people.
It isn't particularly difficult to find 'underclass' Polish people in Poland, just as it isn't particularly difficult to meet 'chavs' in the UK. If you are unaware of this, then either you don't know Poland, or else you (for whatever reason) choose not to notice such people.
Again, my point is this: Why should these people have the right to live in the UK
Why should British people have the right to live in Britain?
Because they are British, I'd imagine.
but not our European brothers and sisters, who are better educated and work harder?
I don't accept that our European brothers either (a) are better educated or (b) work harder. Presumably you have only ever met the tiny subset of Polish people who speak English well. Have you ever been to an 'Urząd' in Poland?
If you wish to meet the Polish underclass, if you come to my city I'm perfectly happy to direct you to places you would be likely to meet them. Have fun :)
I'm sure you wouldn't be happy if you received the same ignorant xenophobic abuse as an immigrant that some posters here say about Poles in the UK.
I haven't written any xenophobic abuse.
I've seen lots of abuse from yourself to your own people, however.
One of your arguments against British 'chavs' is their lack of knowledge of foreign languages. Do you speak any?
