I thought they were a good idea to encourage people to save, but that the £250 wasn't enough money to make a real difference anyway. We'll probbaly set up a savings account ourselves, but I know many people wouldn't - but would those people carry on contributing to a child trust fund anyway?
TBH I don't really object to max124's opinion. We live on an estate where about half of the properties are housing association owned. Our old neighbours were a family who had more children that they didn't want to and couldn't look after, in order to get a bigger council house. None of them worked - and the kids freely told us that dad spent his benefits in the pub & the bookies! The kids were often dirty, got very little parental attention and were generally a bit neglected. We found it very annoying that we were waiting to start a family so that we could afford to do so, and that we were struggling to pay our mortgage, when they got given a bigger house by popping out more unwanted kids (the 7th got them moved).
Most parents pay taxes (as a couple if one stays as home) and many SAHMs used to work and pay taxes themselves! Most people would want to strive to give their kids a good life too - I can't imagine there are many people who bother to come on to Mumsnet who are like the family I described above, but some people do give others a bad name.
I do think that there is something wrong with a society where refusing to work and having kids you don't want, means that you can be better off than people who want to work to get a good life for their children!
