Is there an effect both positive or negative to the county's economy when couples have plenty children?
But at the moment, what is the viability of having many children especially as it could reduce the per capital income.
There's a negative and positive effects, the negative is overpopulation. When there's an overpopulation crisis in a country it always affects the growth of that county as there's increase in crime rate due to so many individuals been out of school, job etc. When the government's of the nation doesn't have the wisdom to make use of the overpopulation to the benefits of the country it affects the country's overall performance and you can notice this happening in most third world countries.
The world is going digit and things can now be done with robots and devices that weren't possible in the past, we don't need overpopulation in the world anymore and the rate at which children are produced should be reduced by each family depending on their financial strength.
It's as though no one has ever considered the problems associated with overpopulation. But allow me to enlighten you: there is more to the story than first appears. Is there a direct correlation between population growth and the decline of third-world nations? You have a very limited perspective
Considering this bright new future of robots and high-tech devices, didn't we also witness the spectacular ascent of Bitcoin when skeptics like you questioned its viability? The digital era offers both benefits and difficulties. Maybe we should prioritize skill development and education instead of setting a cap on the number of children. The true power is in that area. Or maybe that's too complicated for you to enjoy?
