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.
I would say there are both positive and negative effects to a country’s economy when marriages/couples produce a lot of children.
Admittedly, in the past, people may have actually given birth to a lot of children so as to have hands who would work the fields as things were mostly done manually and wouldn’t require payment. A full belly was payment enough. Another reason was perhaps due to ignorance and lack of family planning.
Today, people are more enlightened and having lots of children isn’t as trendy as it seemed to be back then. We don’t actually need a lot of people working the fields anymore as difficult tasks then have been made easier with technology. It’s now also expensive having and properly bringing up a lot of children. A family that’s managing with an average income and a large family, there would definitely not be enough to go around. Thanks to inflation
Today, People are somewhat still ignorant and don’t know or care little about family planning end up having lots of children. More than they could possibly handle.
An average/lower income household that produces a lot of children that end up having little to no education and probably no skills too, would in most cases add to the negative effects of the country’s economy.
If the government of a country can’t efficiently manage its resources to adequately suit the needs of the general population, reduce the poverty rate and generally make life better, it should start with aggressively educating its citizens on the need for family planning, as well as the importance of skill acquisition. An idle society could quickly become a crime ridden society, also adding to the negative effects to a country’s economy and growth.
