but what about the economists who calculate that we don't have enough people to support our economic and social growth and social needs?

Don, I know your intentions are good but you still miss the critical issue. The response to a lack of social resources for the population is not to have a cull, it is to build more resources.

This is not an unprecedented situation, we had a booming population in the post war period and we bloody well went out and built millions of new homes in suburbs and new towns. And we did it all at a time when the nation was pretty bankrupt.

All we lack now is the honesty and the will.
