That last point is always been the way I've seen it - especially here in Australia, the idea that anyone would risk their lives and travel half way across the world in subhuman conditions just to be able to spend their life bumming off social security seems pretty laughable. Indeed they're exactly the sort of people I'd think we need more of in this country, yet neither side of politics is budging from this absurd (and probably illegal) position of not allowing anyone that arrives by boat an option to even apply for asylum on our shores.
