We grew up in societies that promote individual happiness, wealth and health, marriage – if at all – based on sexual attraction and being-in-love, and kids – too, if at all – as the ultimate (and last) bit of this happiness.
After job, carreer, car, house, 2nd car etc. pp.
But looking just 150 years back, having kids was necessary for most people. Kids guaranteed your pension.
And in many places around the world, they still do.
