A lot of this makes sense during times of scarce population
It always makes sense when you are competing for who has the most votes and the immigrants are multiplying like rabbits.
If we don't reproduce well above replacement rates, our culture dies. Sorry these are damned facts.
This is inevitable to some degree as the population grows and resources become more sought after.
Your Malthusian delusion is unwarranted. Resources are inexorably getting cheaper. Iron used to be a precious metal. Did you not see the chart that I quoted from the Economist magazine in my seminal essay several years ago.
You will probably need a week or two of studying the thread slowly.
I will be the first to admit I needed a week or two to fully absorb the following works of AnonyMint.
The Rise of Knowledge
I can accept that resources are getting cheaper from the chart & increasing population doesn't necessarily lead to scarcity, my point was that a) controlling them becomes more sought after (eg, Western wars in ME, South China Sea, Russian gas to Europe) and b) as population grows people look to move where life is "better" (natives believe their culture is being diluted - which I think is inevitable). Sometimes b) comes as a result of a).
If coincube needs a few weeks, I will probably need a few years.
