Also in response to “why do people have children if they can’t look after them or pay for childcare?”
Errr because not everyone is super rational, responsible, always makes financially motivated decisions or is capable of knowing exactly how their circumstances or the amount of support given by the government might change for the better or worse in the future. Especially when it comes to emotionally motivated decisions like having children.
You might as well ask, why do people have kids at all with the looming threat of climate change? Or, why do people get credit cards? Or, why do people eat cake and red meat ever when they know rationally that a kale and lentil diet is better for them? Or, why do people get married ever when the divorce rate is so high? Or, why does anyone buy a car when a bike and the train are cheaper, healthier and better for the environment?
Or even, why do people have kids, when one day those kids will have kids if their own and ask them to help with childcare? May as well just not bother.
How many of your life decisions are honestly motivated by a rational cold cost benefit analysis? And if yours are, do you think that’s the usual way, or do you recognise that the majority of human behaviour is more erratic, emotional and differently motivated than that?
