Are you kidding Wombat?
The price you pay for something is rarely linked to what it's worth to you!
That kind of black and white statement avoids the point entirely. My willingness to pay £1.30 for a litre of diesel in no way represents what I think that litre is worth. I have no choice but to pay whatever they charge. Expanding on that analogy, the high oil prices we are paying are being manipulated by OPEC. They could increase supply in order to reduce price at the pumps, but they have us over a barrel (excuse the pun), and would prefer to keep supply low and prices high. They would also say that the market is 'bearing' the price.
Just because going to Goodwood is voluntary and there will always be those with more money to throw at these things than others, does not excuse the blatant profiteering. IMHO of course.
