With inherited liberal principles, I feel that the free movement of all people is a good thing and one to be encouraged. ... The Declaration of Human Rights has for one of its Articles the right of the human being to take a nationality, to change it, and not to be denied the right arbitrarily to change it. I realise it is not as easy as that, but most of the difficulties are definable difficulties based on facts and situations which the economic planners now available to Government Departments should be able to grasp and measure. I believe that the basic problem which prevents more immigration is an economic one. ... [T]here is a nearer approach to the ideal of universal admission in the United States than there is here. I think we could learn something from that. ... If we were to work out some form of migration policy based on these lines we would be doing some service to that free movement of populations which is a vital prerequisite to understanding in all parts of the world.
