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.
When a family has many children it is like a double edged sword for the country. The advantage is of course there will be more young people who can be used as workers and military, and then consumption and productivity will increase because of this young generation. But it can also cause losses for the country because with more young people it means that crime and unemployment rates can increase.
But in general, having many children is actually very beneficial for a country, but only if it is managed properly by the state, especially the family. Because if it is not managed properly, such as not providing education, health, etc., it will cause many problems which will become a burden for the country.
