No, it shouldn't. All of you who try and put arbitrary (and quite frankly worrying) targets on immigration are deluding yourselves, because you aren't aware of how economically beneficial immigration is to our economy - the reason the conservatives have not and will not reduce immigration to their target is because even they know how economically advantageous it is (it's nothing to do with not having control, the EU has allowed member states the ability to control its immigration since 2004...). The problems with immigration are purely social ones which can be overcome with better integration.
All you ranting it should be 10,000, 1,000, 100,000 are so ****ing stupid and aren't aware of how badly you'd damage the economy, just because you don't like seeing a few more black people in your towns.
