Yawn.
Damn foreigners. Take take take.
If they earn their money, then they can do as they please with it (same as you). You forget that the work they undertake helps this country in the first place.

how did we cope before?

oh yeah, millions was not unemployed?
I would imagine it's nice for most people here, living in very nice areas, and having great jobs. But down the ladder things are not so nice.
Take my work for example, over the past few years we have seen a massive increase in foreign lorry drivers that can hardly speak English (If at all in most cases, which makes things very hard).
And the warehouse (Pickers in this case) most are now foreigners from agency's. Now these are ok payed jobs (23k a year for a picker) and plenty of English people would do it, so we are not talking jobs the brits would not do here.
Oh and just to add, the agency we use is called "Industria" and is mainly for all the foreigners to sign up and is slightly cheaper (But saves the company a couple of quid, not a lot mind). And we have plenty of brits coming to my gate asking if we have any jobs going.
I just hope my children do well in school and uni etc. else as things are for none skilled jobs they will be screwed (Even semi-skilled like lorry drivers are having a tough time getting jobs)
Same with jobs like...
Taxi drivers.
Car washes.
Warehouse workers.
Builders.
Decorators.
Gardner's.
Kitchen fitters.
Plumbers.
Plasters.
Not exactly bottom of the pile jobs that natives do not want is it.
And lets not get started on how rubbish our borders are, the amount of illegals we get on the back of our loads from France is shocking.
