If my wife went to prison then she might lose her job. I would continue to look after the kids by frequently working from home and pay all the bills as I am the greater wage earner. The kids would be looked after and have a roof over their heads.
If I went to prison then I would 100% lose my job, we would probably lose the house as my wife couldn't get anywhere near paying the bills. She can't work from home and so couldn't look after the kids as well as I could. Thr kids lives would be irreparably affected.
But she would get a lenient sentence... because mother?
Or you could actually read what's being discussed and see it relates to single parent families, so it 'should' be applied equally (as much as anything is) whether the single parent is male or female. It's just framed this way as 90% of single parents are female.
