What are the differences between Scotland and Poland?

I have noticed loads of polish folk are comming into my school. Why is there suddenly so many polish people. By the way I don't mind, I am just curious.

I heard that it is because we get so much money in this country, and they don't get as much. But that they don't understand that in Poland it costs less to live than in the UK.

Also, I heard that we have the highest living costs in the world, is that true?

Thanks in advance.
Polish people can earn massive amounts of money here in the UK in comparison to what they can earn in their own country.
On top of that, our government give them housing and benefits, even for children of theirs that aren't even living in this country. I'm a single guy, a UK citizen and I can't even get a council house here in Oxford while there are many reserved for immigrants.
The UK has one of the highest living costs in the world. Scotland has probably the lower end of UK living costs in most parts (excluding Edinburgh) which is what attracts Polish people.
A lot of them share living costs by fitting 8 or 10 people in a 3 bedroom house and sending the money they earn back home to their families in Poland, therefore taking money out of our economy and bleeding our welfare system dry, making our taxes go up.
That is why there are so many Polish people in your school - because of the state our Government has let our country get into in regards to immigration.
