Well, you have the Australia concept of being a 'wealthy' nation only because our population doesn't grow for want of Boat People and New Zealanders or because our women work long hours to keep up with the high cost of living a certain lifestyle with the latest 'technology'.
In essence, if Australia was OPENED UP and the population here suddenly boomed, then - like a Pandora Box, the rest of the World's population might decline due to our 'Minimalistic' nature?
We are anti-youth and pro-aged care. Don't believe the TV, it just doesn't relate to here and is still stuck in America you could say. The statistics prove that we have the highest ratio of Aged in the world. So there you have it - we aren't pro-youth like an over-populated Mexico or India, USA, etc.
eg: One nation has a booming, self-sufficient population growth. Two Adults (hetero) have five kids.
Another nation with a high divorce rate has one kid with two sets of parents. So this kid is surrounded by a sense of wisdom and maturity, etc.
So the chances of the kids of the first nation just breeding and the kid from the second nation achieving.
Alas, the first provides stupidity/weakness and over-population, the other doesn't breed at all.
So you see why Australia is why it is and what its real agenda for the world is. Forget about the position of Prime Minister regardless of who it is - as the 'leader' of this nation. They haven't a clue let alone a sense of true empowerment here.
Also, the fact that Australia - if it isn't opened up: provides a living example of 'quality' of living rather than quantity. That is that we become long-lived: longevity and I don't mean by wealth. Something else entirely ...but thats another secret
