High prices? HAH!
I love the way the US thinks it's oil prices are high. $4 a gallon? I live in the UK. Prices here are currently £1.35 a litre, or about $8.16 a US gallon.
To fill up my car costs about $100. I haven't been able to afford to put more than about a quarter of a tank in at a time for about 3 years.
I agree that the value has been artificially increased to maximise profits. In the UK, we had a blockade at the largest UK refinery (about 2 miles from my front door) about 8 years ago. It brought the country to a virtual standstill. Why? Because petrol had increased to over 80p a litre. We're now not far off double that. In 8 years! For some reason, the more recent strikes and blockades have been poorly attended and far less effective.
It could be argued that someone is pulling the strings to make sure it doesn't happen...
