1. If it was scrapped it would be unfair on neighbouring nations. Especially ridiculous considering the UK is one of the countries that was actively involved in destabilising the middle East.
2. How are they grifters? They apply for asylum. If they get it, they’re the real deal. If they don’t, they’re deported. What’s there to oppose there?
3. Context is relevant. If you care about spending, why care about asylum spending more than oil subsidies?
4. You talk about resettlement programs and how they’re a good way of doing things. How about the countries who destabilised these nations, takes on those seeking asylum? In which case Turkey should bear zero Afghan or Iraqi immigrants, and the western world should bear all of them. Or does it only work one way, in your mind?

Overall I am under no illusions that immigration is an issue in the UK, and is simply being peddled by those who run our media and economy, in order to distract people from real concrete issues like corruption, collusion, homelessness, poverty, etc. like they distracted you.
