No one at all answered my question about whether or not we can support the current level of immigration. The lack of response tells its own story imo. Everyone knows we can't.
Ok, I'll bite:
Let me ask you something, net migration was recorded at 318,000 during 2014. How many of you really believe in their heart of hearts, that we can continue to support these levels?
Well, let's go through the problems in this statement: the first and most glaring is that half of that net migration was non-EU anyway, and a sizeable chunk of the EU migration - around 80,000 - was UK nationals returning anyway.
The second is the presumption that immigration will simply carry on at current levels indefinitely. I see little reason to think that is true. As living standards rise in Eastern Europe I would expect to see migration to the UK from these countries fall. I also question whether we're really seeing immigration on this scale. It seems to me that a large proportion, probably a majority, of recent EU immigrants are better characterised as migrant labour. It is likely they will return home later in their lives.
Then there's the problem that leaving the EU may not end free movement of Labour anyway. Euroskeptics like to point to Norway and Switzerland as successful model countries with free access to EU markets - as Euroskeptics claim we will continue to have - but the terms of their access require them to allow free movement of labour. It's pretty clear that much of Europe views this as be a non-negotiable feature of the market. If we want equal access to the EU markets we will, most likely, be forced to accept free movement of labour anyway.
So, I don't really accept your premise that immigration will be on that scale anyway or your premise that a 'No' vote would end it.
Having said that, I think that the levels of immigration we're experiencing are primarily beneficial to this country and will continue to be so, especially as our population ages. Immigrants are typically higher skilled, more flexible and more motivated than the average member of their country - pretty much by definition since they're the ones willing to travel overseas to better their lives - and so immigrants are of great benefit to the countries that accept them. This does not mean there aren't issues with housing and infrastructure to overcome but I see no reason, at all, to believe that these are not eminently solvable.
