"I don't see how you can keep people here if they want to go", the girl said. "What's the Commonwealth or Empire or whatever they call it these days - what's it for?
You can go to Australia if you want to, can't you?"

"You can at present, but it's got to be controlled. People can't always do the things they want to."

"I'm sick of the word control", said Jennifer. "We didn't have to have all these controls before the war."

"We had three million unemployed instead. - I'll give you a better reason than the money why people ought to stay here -
to do a good job for the world.
Here in England we've got the most advanced form of government of any country in the world.(...)
But what this country has been trying to do, is to plan a new form of government and put it into practice, a new form of democracy where everyone will get a square deal. When we have shown it can be done, the world will copy it, all right.
But it can't be worked out if people are allowed to run away to other countries. It's their job to stay here and get this one right."

Jennifer said, "You mean, one ought to stay here because there's an experiment in Socialism going on, and if we go away we'll spoil it?"

"That's right."
