Although Mr., Mell's job as a teacher gives him a measure of respectability he would not enjoy doing "unskilled" labor, it clearly doesn't pay well: he can't afford a new pair of boots, and has been wearing the old ones for so long that they can't even be repaired. Given the state of the classroom, however, it's equally clear that the school isn't spending its money on educating its students well. In fact, Mr. Creakle basically views his school as a business venture, which Dickens (a proponent of education reform) suggests undermines the role that education ought to have in shaping young people's minds and characters.
