But like Neil M so rightly put in the other thread, a lot of the money they earn goes out of the country, I'll quote him if he doesn't mind as it was such a spot on post that its pointless me adding to it.
The key thing is the amount of money leaving our economy, You get 10 polish living in a house, splitting the rent and council tax 10 ways, then sending the majority of their earnings back to families in poland.
The pound being strong against other currencies means that the money was almost tripling when it went abroad.
This is happening on a large scale, in almost every town in the UK.
Once the money has gone its not coming back either, its not like you earn money in this country, you spend it with companies in this country, who employ people in this country who's wages are then spent with companies in this country and so it all goes round.
Then there is the additional burden on Councils because the increased population is putting a strain on resources like education, housing etc etc
Not to mention the additional strain on healthcare and policing.
Unfortunately giving access to an exploitable resource for employers here in the UK is a positive thing, it has far more negative effects than people will admit to.
So if those of you who feel its a positive thing please let me hear the case for the defence
