Even your own link reiterated everything I said: It depends on the individual and everything else going on in ones life.

You live in a child oppressive society like Asia or the United States? No shit it's harder to be happier than without children

Income, society, your partner, your parents and more importantly: your own ability to endure the ups and downs of it all matter when it comes to your respective happiness as a parent.

But it comes down to the individual and it's each individual's choice, period.

I am in America, but I also married into a minority group who is immensely supportive. No question my life feels more enriched having had children because I love being with the family my wife and I created.

Sorry, for the late response, I was enjoying my weekend and my life.
