In the UK, there are two sorts of schools: state schools, which are funded by the government, and private schools, which are paid for by the parents. Because school fees for private schools are high, most of the children who go to them come from wealthy families.
Mr Wackford Squeers is a character from Charles Dickens' Nicholas Nickleby. He is the headmaster of Dotheboys Hall where unwanted children are sent. He abuses the children and is incredibly cruel. Later on in the book, he is arrested and sentenced to be deported to Australia.
