I’ve heard it said on the wireless on a number of occasions that an immigration coming to the UK has to be earning around £45kpa before they’re a net contributor, and this figure doubles if they bring just one dependent. I don’t know where this figure came from and it needs fact checking, I know, but feels about right, although there are also myriad variables such as where they choose to live.
So, I don’t know if I completely agree with the “cut immigration and get poorer” option. Of course, we should always help genuine asylum seekers, but we cannot do that ad infinitum without also having the balance of the right quota of contributors as well.
One of the biggest problems that I can see is that our default seems to be that most immigrants claiming asylum are genuine.
Something I think is badly needed is a joined-up process right across Europe. If, for example, immigrants arrive in (say) Greece, we should be able to log their ID (prints, DNA, retina or whatever) and the story they give, who they’re travelling with, where they ultimately want to get to etc. It ought to be fairly straightforward to re-process them at various European borders and cross-check stories etc. for consistency.
