Are you actually for real? What's not right is that people think they have a right to have a child and then not bother to do anything to provide for it.
My friend was deserted and the Father pays nothing
That's very sad for your friend, but the father and mother of this child have more responsibility for the person they created than other people who go to work to pay for their own children do. Because that's whose picking up the pieces. Other families.
apart from the moral highground - there is no solution given here and the underlying problem remains
My friend shouldn't have to work, it should be a basic right to choose
Yes, she had the right to choose not to have a child.
it should be recognised that despite best efforts accidents happen
No one should have the right to force someone else, ie taxpayers, to fund their lifestyles choices. You are ridiculously misguided.
He was expected to leave his four children in the care of his 14 year old daughter
No, he wasn't. He was expected to find suitable childcare. But that wouldn't be a problem if everyone who worked was offered free or very heavily subsidised childcare, would it?
another pithy retort without an actual solution. suitable childdcare costs a lot of money - for 4 children
