Especially when it was £20 to move the whole family (kids were free) to Australia. My great uncle and aunt did just that, after national service he was in business working for Walls ice cream. Took himself and two kids off in early 60s, were in a a Nissen hut for a few weeks til he found a job over there.
Commonly known as the "Ten Pound Pom" scheme [0] which ran from 1945-1972
An incredible return on investment. I bet many ended up with higher wages, better health, better housing etc (though I think about 1/4 ended up returning, at a large expense)
