...you have to adjust for the cost of living. For example, salaries in California, U.S., are some of the highest in this country. But the cost of living is also very high there.
Unfortunately for Australians, the Consumer Prices in United States are 32.44% lower than in Australia.

I always appreciate hearing about the differences between the United States and other countries. Thank you for sharing information about Australia Adam.
