Population growth is a serious matter and significantly under-reported, but for those that do talk about it, I have a hard time remembering anybody relating it to our monetary system. You mention that “current government policies [are] aimed at maximizing population growth.” I can’t see how that can ever change so long as we have the imperative for growth, which is largely dependent on, as mentioned in the post, the need to create more loans to pay off the interest on previous ones. How can government policies, subservient to business-as-usual economic imperatives, be anything but pro-population-growth when the monetary system dictates the need for continual growth? In other words, while you say that “You can’t say what you just did without addressing policies aimed at maximizing population growth,” I’d add that we can’t talk about population growth without talking about our monetary system.
About Norway and oil, well, Denmark also has few people but doesn’t have the oil that Norway does. In the opposite sense, Nigeria has nearly 200 million people but is nonetheless a major oil exporter (granted, your average Nigerian consumes much less oil than your average Norwegian, but that’s another story).
And of course, Japan would be in a much better position if it had the population levels of New Zealand (where I currently am for the time being), which, as far as I remember, has something like fourty sheep for every person. Or in other words, a low population-to-land ratio.
