Yes, this is very much a societal responsibility which is ignored. Most is us know men (usually dad sometimes mum)who is open about the non-payment of maintenance which is accepted by family, friends, colleagues. I have never heard any such man openly criticised or challenged on his behaviour. Instead, the issue is pushed aside as personal, other people's business, there's probably more to it, mum earns a fortune so why should he pay.
The result is that single mums are blamed. You see it on this site all the time wrapped up as 'poor choices'. Victim blaming in all it's glory: you shouldn't have had a child with a man who (sometimes twenty years plus after getting together) wouldn't support his children. That a father doesn't support his children is somehow the absolute blame of the mother.
And so single mums must struggle to manage on their own. If they dare complain, well, you should have married a better man. If you choose part-time work or are stuck on minimum wage work, you are made to feel bottom of the pile, expecting others to bail you out. The others being the amazing tax payer who gets off their backside and works whilst you enjoy your poor choices. Same tax payers who know men who don't support their kids, who eat with them, sleep with them, socialise with them whilst casting a superior eye over the struggling ex. Single mums who manage, work full time, earn good money can expect to be told that they are neglecting their children, that relentlessly pursuing g a career is a bad thing, or are subjected to people gossiping about the fact you've been on holiday and how on earth can someone like her afford that?
Smoking, drink- driving. Excellent examples of how society can change its attitude and influence opinion. It is time we all refused to accept the abuse of children by one of their parents - because that is exactly what it is - and refused to have these men in our lives. Sadly, misogyny is alive and well, even amongst communities like this made up mainly of women. We are our own worst enemies, we really are.
