The thing about tax in the UK is that incomes reflect higher costs, take the US dollar conversion, ?1 equals roughly $2, but the minimum wage in the UK is around about double (I don't have the exact figure). In many of these countries with really cheap fuel, their wages are very low as well. It is all well and good if you pay 7 pence a litre, but if you only earn a pound an hour, and someone in the UK earns ?15 an hour, the hit to their income of the fuel price is lesser. So for someone in these countries the cheap fuel really isn't.Trust me Matt, England is not the best country to live in. The crime level is very high. Also, the taxation is tremendously high.
I was talking to this supply teacher in our History lesson. She said that her Brother worked in Hafuf (A place in Saudi Arabia). She told me that it is 7p per liter. Here in England, (at the moment) it is ?1.03 for Unleaded Petrol :
Really the only way to reliably measure the cost of fuel is by using a measure that doesn't depend on the value of the currency, fuel cost as a proportion of gross income would be a way of doing that. Basically no matter how cheap the fuel is, people still complain about how expensive it is.
On a side note, I paid AU$1.55.9 per litre for fuel last week.
