A sustainable population requires a fertility rate of around two or slightly more, on average, as suggested by mathematics. A lower fertility rate implies that children are seen as less useful. When subscribing to a product, its utility normally increases over time, accelerating its value and potentially reducing its cost.

The negative price means, if you do not sell it, nothing would be bought from you and if you sell, it will be definitely bought. The less children are ‘utilized’ in a society, the more expensive they become in the subsequent cycle, until they are perceived as a problem rather than a solution, making the prospect of having children less attractive to families. ...
