Are you seriously suggesting that she's starving herself and her child deliberately in order to score some sort of political point, and if so what point would that be?

Details are slightly unclear because not everyone's employment and sexual history is on the internet for the benefit of their book reviewers, but it appears that the shiftwork required of the job made it extremely hard to find childcare, and the cost of childcare+commuting to work made working non-viable.

I've no idea where the father is, you could ask about for him? As for the "shouldn't have child" argument, you can't return children for a refund when you become unemployed nor can you ebay them to recoup your costs.
