I agree that we do not all benefit from (global) capitalism equally but
My bil claims that the simple fact of being born in the UK, with all our benefits (NHS, free education, etc.) is equivalent to a birthright of £1 million.
The movement of peoples across the world, not simply because of war/persecution but also for economic reasons, suggests, strongly, that this birthright is founded on a global inequity, with the impoverishment far, far from the UK.
I must admit, I'm sneakily in favour of open borders, full stop. Not even just for the victims of persecution and atrocity. Capital is allowed to roam free, why not people?
The fact that, if borders were open, there would be a vast, shocking, amazing decline in the living standards most UK citizens is, I think, a cause for thought.
We would hate that. Quite rightly. And yet we tolerate that for other people.
