the question you need to be asking is what the average persons wage is in these countries....I would bet that it would all even out...........
let me use a pint of beer for example, no matter what country I went to the beer usually ended up costing $5-$7 US per, regardless of the currency.
countries I have tested this theory in...
Australia (pitchers of
VB were cheaper though)
Singapore (mmmm Tiger beer)
Hong Kong
Kuala Lampur
and even though fuel is expensive, last time I was in Germany I saw an awful lot of very nice cars on the road
