Countries that has qol, they can have kids, and they should deffo implement policies so generations continue. However, in countries like where I come from, qol is poor, so I don't want anybody to this shitshow.
Even if the quality of life in your country is not good, it does not mean that your children will not have a better life because it depends on your financial resources.
I am also from a 3rd world country and my economy is not as good as many other countries. Not to brag but our life is a little better because the financial situation is not so bad.
Having children should be a personal decision as it involves many factors such as maintaining the family lineage, the couple's desire for children to be a bond and make family life happier. Or they can also be the motivation for us to try harder in life...
I have 2 kids and I have to admit my life has gotten a little busier since having them. But when we had children, our family became happier, more fulfilled and more connected. So as an experienced person, I encourage having children but it needs to be planned and within financial means.
