None of these policies make sense at all whichever way we do it. They're costly schemes that go to attack an issue that actually is not really an issue, we're talking about less than 50,000 people per year, less than 10% of total immigration. It has been made into an issue purely because of the negativity and costs involved, costs that are a result of Tory policy and the shambolic public sector.
You only have to look into where most of the costs come from, they come from housing and feeding people whilst applications are processed, that's it. Slow application processing isn't because there are too many applications, it's because the policy is purposely complicated and the Home Office isn't resourced to do the work.
Rwanda vastly increases costs even more by adding an extra step in the process, ie, people are sent somewhere after being processed. All they're hoping is that it will act as a deterrent and so it will reduce costs in the long run but there's no evidence of this.
Why not just accelerate the application process so that it becomes cheaper? As some claim, if migrants are here for a free lunch then why not remove it by ensuring that applications are processed faster?
Either way it makes no sense that we pay so much and obsess over such a tiny percentage of immigration. It represents less than 10% of immigration and yet nobody is doing a single thing about the other 90%.
