Exactly. If the government reduced the tax on the fuel (and don't forget, every time that the physical cost of the fuel itself goes up the tax goes up twice as much!), then we could start paying sensible money for our fuel which would in turn lead to cheaper food in our supermarkets, which would mean that we would have more spare to pay our mortgages with or buy luxury goods, which would lead to a kick start in the economy and we wouldn't have to worry about this credit crunch malarky.
However, getting the government to understand all that is another matter...
