Is it?
Why?
Money plays the same in any culture.
You're actually suggesting that being Christian is a disadvantage in acquiring gasoline? Is it easier to get oil from Nigeria than from Saudi Arabia?
Btw their PM until about a week ago is an atheist. Would that be a problem?
Well for one the Australians don't hate us like alot of the Saudis and OPEC countries do, thats a start.
"Hate" doesn't enter into business. And in any case all that oil, whether from Kuwait or Kookaburra or Caracas, goes on an international market. The Aussies don't get to set a price for that market any more than anyone else does.
The bottom line is that the end product costs the same whether you're Christian or Jewish or Hidu, whether you speak English or Japanese or Sanskrit. The idea of oil somehow being cheaper because it's in English or processed by Christians is absurd.
