Perhaps you would like to take a trip into the past and see why
birthrate use to be high.
In the old days, technology is backward, no phones, no internet, no
TV, no nothing. The sun sets, there is no light, everyone goes
home, there is nothing to do, so . . . . . . .
In the old days, people gets married whenever they are fertile,
though arranged marriage mostly. You have a husband/wife, what do
you do? Well, do what a couple is suppose to do of course!
And to the modern times,
With good technology, you can work round the clock. Even if you
don't work, there is so much entertainment. So, bed time activities
reduces
We are freedom of love now, everyone loves it. But unfortunately,
Ying Yuan does not seems to happen to everyone. For some, it even
happens so late, that by the time it comes, the ladies are no
longer fertile or can only bear one or two babies, unlike the olden
times. My grandparents each has 10 childrens!!!
Also, in the old days, having a family is something natural,
everyone will have it. In modern times, people starts to question
why they even need to get married and have a family, especially
among the well educated.
So, where is the problem? You decide.
