Any strategy that depends on on growth ad infinitum is doomed to failure.
Want to solve global warming? Forget about carbon taxes, cap and trade etc - have fewer people in the world.
One of the things that makes Canada so nice to live in, and so desirable a destination for immigrants is that it isn't packed wall-to-wall with people. Why do we want to change that? I don't and in fact since it looks like Canada under Trudeau(*) is giving up on having a manufacturing base and is content to do nothing but sell our resources we should be trying to reduce our population as much as possible so that the resource extraction income is divided by as few people as possible.
(*) to be fair he isn't the only PM we've had taking us in that direction but Trudeau really seems intent on accelerating the process with China.
