Bringing a child into the world knowing it will end up in poverty is irresponsible
And the child should be punished for that, should they?
Redundancy, relationship breakdown, death, disability, illness - they can all reduce a families circumstances.
There are people in full time work who can't make ends meet because the minimum wage is not a living wage and top-up benefits such as Universal Credit are not fit for purpose.
There are people who do not have control over their own reproductive choices, over their own finances, over their own lives due to domestic abuse. Austerity makes it more difficult for them to leave.
There are people with chaotic lives, who for whatever reason don't have the ability to rationalise "maybe now isn't a good time to have a baby" so they have one.
There are people who are in contraception and it fails but they either cannot access an abortion or do not want one.
There are a million different circumstances and situations that mean someone cannot easily support a child.
Not a single one if those circumstances is the fault of the child so why should they bear the punishment for it?
