Is there an effect both positive or negative to the county's economy when couples have plenty children?
In the past before the current economic era, around the 15th century and the beginning of the French industrial revolution, having many children was seen as fertility and good for both the family work force and country's also. The labour force was majorly manual and those who worked at the plantations were sort after as able bodied men or women.
But at the moment, what is the viability of having many children especially as it could reduce the per capital income.
Having many children without corresponding means of taking good care of them all is wrong and of a negative effect to a nation's economy. And when I say taking care of them is not just only in the aspect of being able to provide food and shelter for these multitude of children per family but been able to give them sound education that they become assets to the society not burden.
And for a nation that's already populated it will be unwise to still give birth to many children in such a country wether you have the resource to take care of them or not.... The concern is reducing the total population of the country so the nation's resources and opportunities could reach almost everyone near evenly.
But for a nation with limited populace having many children isn't only a blessing to the family but the nation as it's workforce would grow geometrical, let say in next ten years to deliver the economy especially for a production nation.
