Tell that to anyone who is relying on Social Security for any of their retirement money.
If you invert the pyramid the scheme collapses. Without children, the pointy end points down.
I am discussing the finances of the family, not that socialist Ponzi scheme. NO ONE has children because they think "My children will pay into the social security system and help me retire!!"
When it comes to having children, their tax contributions to society at large is irrelevant to the decision.
