The more relevant comparison is to the aid budget. That’s where we spend money altruistically to improve the lives of foreigners who have been dealt a really shit hand in life through no fault of their own.
Also while asylum seekers are still in the processing stage the funds directly trade off against one another.
That calculation pushes me heavily against expanding asylum other than for those we have a specific responsibility for.
Because the cost to save a life through effective aid interventions (and the UK has one of the best/most evidence-driven programmes) is about £4k.
The cost of a year of typical asylum seeker costs is £30-40k.
Absent any specific personal obligation, I can’t see any justification for spending eight lives every single year on each asylum applicant.
Added to that that it’s unpopular (which has to matter in a democracy) and turns people against all forms of migration (which is generally a positive force, at least done right).
Where do you think I’ve gone wrong in my thinking on this?
