I think it is hugely important to teach children good financial sense and awareness. It should be a combination of school and parents.
However, with the high levels of personal debt and finacial crisis in this country I'm not sure that enough adults are savvy enough to be able to teach their children effectively.
For example, I was homeless when I was 15, living in a bedsit by the time I was 16 and had to manage bills etc. Unfortunately no one taught me, there was no internet then, my only information source was my bank.
I ened up in dire straits and it's only really since my early twenties that I have learnt how banks etc make their money, what constitutes "good" and "bad" debt, how to budget properly and what is really a good deal.
My partner had two parents at home who spent every penny they earnt every week on shite, he is utterly awful with money. He has no idea how to shop around for a good bank account,he can't manage credit properly.
Many of my friends have high personal debt, no savings, cars on hp etc.
It seems to be more and more common for people to use credit as a lifestyle necessity rather than save for things.
The "I want it now" generation is here in force and unless we can convince our children that this should not be the norm then they will carry on making exactly the same mistakes that we are.
