If you are "well off yourself", then your partner should do what? Nothing except pleasing your desires? Just to please you & take care of you in all ways because you provide money & shelter?
Probably some people wants that, but I'm not.
My mindset is like this, if there was no woman who support me during my process, then I make sure I will marry with woman which the value equal with me. If I'm well off, I will marry with well off woman or no marriage at all.
But if you look at it from the point of view of an individual, then rejecting heirs because they are expensive to raise is simply absurd. Then everything that this person has earned in his life will go to no one knows who. So he ended up earning money not even for his own children, but essentially for other people's children. Isn't that silly?
I don't think it's silly.
Just like the content I watch on Instagram "Plan A: Married by 28, have kids by 30, Plan B: Be That Cool Uncle".
I'm more happier to see my nephew or someone else kids appreciate my small gift instead of living with someone who can't be grateful even I've give 80% of my money and keep pushing to earn more, it's more or less like living in hell.
