... This shifts power to food exporters from food importers, and the way to make up the difference is to produce more of whatever it is you can produce, and that requires more people I'd think.
It requires more poeple only when there is labor shortage and in this case
only. When population grows that fast there is no labor shortage, there is oversupply of labor. That's why coffee tree planters are paid less than $2 per day.
That's why also their agriculture is under mechanized and production per capita is much less that anywhere else in the world.
Think about China or India. Their power comes from massive amounts of human capital, and despite a historic lack of other capital they are now world players. I would think the same thing should work other places. Or do you make a distinction between population and population growth?
What makes China and India a "World Power" is the 55 millions chinese (and Indians in similar numbers) who made up the middle-class consumer (who earn as much as a middle class in the West and pay taxes in a system like ours).
That's the 5% of China and maybe 6% of India which make them global players of the might equivalent to France.
Not the one billion of poors (who have yet to pay a single rupiah in taxes).
China and India have been spectacularly stable (unlike Africa). Yet it took them until 2005 for their economy to be noticed on financial markets.
IMO their population growth has been a drag, or at best a null factor in their economical, political, cultural and military might today.
They would be as powerful with 3x less poeple IMO.
Is there a clear example of a well off country that raised it's population and became a poor country?
I don't have document to support that, but I'm absolutely sure that Africans and Indians et others were much better off 100 years ago than today.
100 years ago poeple were living off the best land in the safest places to be. Today you will find millions of poeple where no one lived before, in floodable bassins and deserts with record low rainfalls. In Brasil poeple live in shacks on mud-slinding hills. Most of thrid world poeple don't have access to modern facilities and technologies, save through international aid.
By contrast, the west has improved decade after decade the wellbeing and confort of its inhabitants.
Here's another point I can't back up with fact. One would expect economic activity to produce at least a 5%, so with population growth at less than 5% I'd think scaling up the number of people working to be good for a nation.
What you miss completely is that what is important is not the total GDP, but GDP per capita.
GDP increase based on population growth alone cannot be considered as an economical developement.
Now I do recognize on a world scale with a long term time line it is dangerous to infinitely increase our population with finite space, but I don't think that is the issue here. It is in a nations self interest to have a higher percent of the total population and there is only one good way to do that; grow.
I think the sistuation is already dangerous. But we don't know exactely what are the dangers exactely.
It's a little bit like global warming: We know there could be problems but we don't know which one.
Till which point can they go, nobody knows.
What is sure is that it cost less to help 300,000 popel stranded in flooded areas than 2,5 millions. It cost less to sent in emergency food for 100,000 than for 1,000,000. That's what I know.
