it depends on what cheeseburger you're talking about. The dollar menu cheeseburger is around $.99 but it's a pathetic little thing, the normal size ones are closer to $3. Our minimum wage here is $10.25 AU, but that isn't enough to actually live without extra government assistance or a second job. According to this website, our cost of living is pretty close to yours. Your food is a lot cheaper, our clothing and gas is a lot cheaper, rent looks pretty close to the same with you guys having the edge, owning property is a little cheaper here.

But looking at the other stats, you guys spend far less than we do on healthcare, you have lower poverty, higher life expectancy, lower infant mortality, and fewer health issues.
At least we have cheaper gas though lol... hell we fight enough wars over the stuff, it SHOULD be cheap here.
