Immigrants make up a very small proportion of the current population. Without doubt some of them may be doing what has been suggested by some posters on this forum. ie lazing around and not working. I have no idea and its unlikely I will find out by reading the Daily Mail.
But we have had a situation for years and years here with white, Anglo-Saxon people doing just what you outline. Why is this not an issue ?
There are exceptions of course but most immigrants move to another country for work. They always have, since time began I would guess. For instance, millions of people fled Europe to go to America and Canada from the late 1700's onwards. There are now more people of Scots-Irish descent in North America than they are in Britain. They were amongst the main protagonists in the Manifest Destiny that populated the Mid West and Cailfornia, making America into the nation it is today. Millions of them went West in covered wagons.
We have a very large Amazon Depot in my home town here in South Wales. It is staffed, almost completely by east Europeans. But the dole queues outside the Job Centres in the surrounding area are overflowing with nice healthy white Welsh people, who can't find a job apparently.
Immigrants have come to Britain to work, most of them at least. If there wasn't job vacancies for them to take, they wouldn't be here !
Why were there job vacancies for them to take in the first place, when we have such huge numbers of unemployed Brits ? Surely those vacancies should have been hoovered up by all those people that have been on the dole for years, some of them second and now third generation "unwaged" long before the likes of the Poles arrived ?
Have you visited anyone in hospital recently ? The NHS would collapse, overnight, if all the immigrants went home !
Most of our people on the dole have claimed every benefit going, while supposedly "looking for work" There is a white, British woman in Tewkesbury that was in the news recently, with 11 children. She is claiming £154.30 A WEEK in Child Benefit alone ! I know some people who don't earn that much a week.
About two or three years ago, the BBC ran a documentary on why Brits are out of work, while new arrivals from East Europe have no trouble finding work. It was filmed in Lincolnshire or Norfolk as I recall. The Brits that featured in the program were truly pathetic and embarrassing. There was a young chap who was offered a job in an Indian restaurant, as a waiter by the owner who was persuaded by the BBC to take part in the experiment. He didn't last two days, but even when the owner had to sack him, he still gave him a really nice curry lunch before he went. The owner seemed very nice and didn't freak out as another employer might have done. I thought he was very patient and understanding.
Another couple of men were employed in a vegetable farm, picking asparagus as I recall. They lasted a few days but eventually were "let go" and the owner had to get one of his Polish staff to go back over the area of the field where they worked, in order to pick up all the stuff that the Brits missed.
There was another couple who worked in a veg packing factory, who performed with similar lack of ability.
All the employers that took part in the program made the same point...if they could get willing, hard-working Brits to do the jobs they would, but generally found them to be lazy, and almost useless, thus explaining why they used eastern European labour instead.
I have every sympathy with people who are out of work, and I appreciate that unemployment is rising, especially among the young. I have been unemployed myself, although thankfully not for very long before I found a new job. But if people like the Poles can uproot their families and find work over here, why can't the Brits find work ?
