John, you start your hypothesis on the assumption that population growth is a good thing. With the world's population growing at an alarming rate this planet will have a hard time sustaining the nearly 15 billion people we expect to feed, educate and support in just a few decades. Not to mention the affects on our environment and resources. The UN predicts it will level off at that point although it is not clear to me what conditions will trigger that.

At 7 billion we have long exceeded the ideal population of 4 billion.

Politicians and business people like the idea of population growth. It increases the number of consumers and therefore artificially helps to grow the economy in the long term.

I believe most Canadians would support an immigration policy that maintains our population at 35 millions.
