YABU, children need the time to be children.
Reading, drawing/colouring in, playing with friends, sleeping in and watching tv are all activities that don't cost money.
As pp's have said, the biggest problem now is that children seem unable to amuse themselves and expect to be continuously entertained and stimulated, preferably with expensive activities.
I spent the summer watching tv, reading, sleeping late, doing homework, drawing, playing in the local farmers field, looking after my cat and dog, and spending time with friends who lived locally.
We didn't do anything that cost money because my parents both worked (mum 5am until around 1pm only) and didn't have any money to spare.
If we were lucky, I was given 20p on a Friday to spend on sweets at the local shop.
It never did me any harm, and my 2 best friends were from more wealthy families and would be off skiing, horse riding, etc, but that's life.
We're not all equal, and never will be, and so our lives also aren't; it's just something you have to learn to deal with.
It certainly isn't a good idea to bring everyone down to the worst level, and it shouldn't be for the state to provide everything for free/subsidised, I already think we live in too much of a nanny state.
Schools are there to provide education, not childcare, that's just a lucky bonus for the time they're in school.
