Why are there so many barriers and restrictions in terms of gaining
employment between the 4 groups of USA+Canada, UK+Ireland, Australia
+NZ and South Africa. They all have common histories, can understand
one another and have common cultural links (to a greater or lesser
extent), and yet the UK and Ireland seem to be trapped in a
multilingual europe, without a desire to become multilingual,
Americans and Canadians are prevented from working easily in London
and vice versa Brits and Irish in the USA (unless you can find a
company that is a multinational etc. etc. and transfer), and the
Australians and New Zealanders face similar problems...
It all seems so stupid that Aussies have to rely on ancestral visas
(which will be, as each generation grows up, ever more impossible), to
work in the UK and brits face equally harsh quota restrictions.
It is a shame, and somehow so wrong that would should be a chance for
people to live and work in such different and far flung parts of the
world, is ruined by regional blocs.
