A most interesting and informative article, Pip. Thank you.

There is much in it that I need to absorb yet, but obviously the problem is considerably more complex than I was aware of. However, with a measure of good will on both sides (a commodity hard come by these days), it would seem that the problem could be solved with some serious negotiation. But then, so could most of the world's problems!

I do not see, however, that these difficulties justify closing international borders to immigration. The advantages far outweigh the occasional problem that manifests itself.
