Why are there so many people in the world?
I am the only important person in the world - I hope we can all agree on that - and everybody else is here only to make my life richer and more fulfilled; that's axiomatic. And I think there's a degree of featherbedding. We could do more with less.
I'm not taking a narrow view of this, mind. I'm not just referring to the comparatively few people I actually meet or deal with. I quite appreciate that it takes a lot to run the entire supply chain from the iron mine to the part in my biro. I can see, from the economic point of view, that there need to be a lot of people in China to drive down the labor cost so that they can produce cheap Incredible Hulks for me, and a large amount of people in the West so that there can be a market for Incredible Hulk stretchables.
I just think that even taking all that into account it should be possible with a little planning to eliminate the need for about two people in three, absolute minimum. A billion people worldwide really should be the absolute outside.
