It's interesting. That would be my thought too, and is how things work in countries such as the US, but in the best-run schools in the UK IT is at the centre of everything, and it works out cheaper. Think about it - a good network-based education setup means no hard copies of books, no paper costs, more efficient telephony and communications. Controversially - and it's the elephant in the classroom - a good IT solution can reduce the number of staff required to run a school. Again, reducing costs (although not teaching staff).
