mrmarket, while I agree with you generally that high expendable incomes = more to spend on gambling and will skew the results, the sad fact is that anyone who lives in Australia will probably be willing to lay a nice wager that a large chunk of our figure comes from low to very low income people who are playing slot machines.
"Mr Wilkie (an Aussie MP) said Australians lost around $14 million a day through poker machines and there were 95,000 people seriously addicted.
'Australia has almost 200,000 poker machines which are among the most dangerous in the world," Mr Wilkie said.
'People routinely lose $1200 an hour gambling on pokies in Australia because they're high-intensity machines with high bet limits, fast games, big jackpots and substantial cash load up capacity."
That's what Alt's picture is referencing: Centrelink is the national welfare organisation; pokies = slots. It's a massive problem here, to the point that ATM's located in pubs with slots have a limit on how much you can withdraw each day and now the Prime Minister has said she's going to pass legislation where you'd need to use a Smart Card with a pre-set limit on it in order to use this machines so it limits the amount you can lose per day. It's an epidemic here.
