Are the lives of immigrants better? Are we importing citizens or slaves? Why are we not interested in improving conditions in their home country? Shouldn't we focus on that first?
Your rhetorical questions don't constitute an argument so forgive me if I misrepresent you but what I think you're saying is:
1. Conditions in the UK might not be good enough, so we should prevent people from immigrating, for their own good, and
2. Fixing problems that create refugees is more important and therefore another reason we should prevent people from immigrating.
To which I say
1. That's a reason we should clean our own house, so we create a safe environment for people looking to come to the UK, and
2. That's a non sequitur at best, and honestly callous; you should try fleeing from war and persecution, and then see how you would feel about returning home to wait for a few more years while 'things get sorted out back home'.
Again, correct me if I have misrepresented your implied argument.
