Gettler used statistics to draw comparisons and this got me to thinking that teachers could get kids to investigate the figures and work out their own comparisons. For example, this paragraph about Macquarie Bank's chief executive Allan Moss:
On $33.5 million, Allan Moss is on a nice little earner, up 58 per cent on the previous year. As The Sydney Morning Herald pointed out, he's worth 446 construction workers, 669 graduate teachers, 335 GPs, or 747 times the average Australian worker.
So there you go, I wonder how many teachers you could get for Allan Moss's salary?
