What do the anti-immigrant right think will happen if we don't help to make poorer countries more worth living in? The young and fit (and mostly men) will come here for a better life, of course. It would be in the best interests of the Priti Patels of the world to help the poorest people to make an acceptable life for themselves at home, if they don't want them here, wouldn't it? 
The fact that it is morally right to spread the wealth of the world out more equitably will pass these people by completely, of course.
