The awful thing is, that there are plenty of us who would welcome this, because we, despite wanting with all our hearts to be stay at home mothers, are unable to, and must go out to work along with our husbands/wives/partners if we want to pay a mortgage on a house big enough to raise a small family in. No spare bedrooms round here, I can tell you.
Longer hours in school and less holidays would massively help - our children wouldn't be shovelled from pillar to post, from childminder to granny, to friend, to holiday playscheme - they'd be attending the same place, with the same staff, consistently, while we were out trying to earn a crust. Some children just don't react too well to constant change/lack of routine/consistent care, and while their mothers would dearly love to be able to provide it 24/7, are unable to for financial reasons.
As for how it's going to be funded - presumably all the working tax credit that goes to parents like me, and many, many others, which is currently being paid to childminders and private holiday playschemes, will go some way towards it, if not the whole way. Childminders round here charge £5 an hour per child. So say 4 children, is £20 per hour (I know they have a lot of expenses so understand that this is no way to become rich) which might pay for two teachers to cover a class?
You ladies who are able to choose to stay at home are very, very lucky.
