Big thx for this amazing comment and for your time @artgirl
Don't have kids if you're only going to use them when you grow old.
Perhaps I'm seeing children being "an investment" because I've spent to many years living around Chinese people (either chinese-malaysians or chinese-singaporians) and that's how they seem to "work". They raise kids so in the future kids would take care of them (parents usually move to live with their own kids, even if they are married and have families). Level of independence in those communities is very ... low.

Yes it is a culture, not only in China but elsewhere too. It's one of the practices we should change as current adults. We are the only ones who can change the future. Let's hope and pray the next generation can do better than us too.
