I'm a little surprised at all this tax furore over fuel duty. When i was lecturing at the University of Teesside ten years ago I was explaining this to my wide eyed students even then.
The British motorist has been regarded as a cash cow by both the prevailing government of the time and the auto industry. Ford and GM used to rely on profits from the UK to prop up their piss poor US industry. Look at the comparative prices for the obvious answers.
The government knows us Brits are wedded to our cars (and look at our motorsport history compared to any other country). To keep us in our cars and put billions into the pockets of big business our 'public transport' was privatised. So its now really private transport. Thus the government has ensured its cash cow for the foreseeable future.
The fuel protests of 2000 highlighted people had had enough at that point. So the government was struggling to find a 'legitimate' means of continued tax rape. Enter the environmental lobby. Hurrah! Governemnt is saved again! The prices can rise - so automatically increasing the tax take - and they can blame someone else. Always important for an incumbant government. The most important thing to remember is that:
the last thing the government wants is for British motorists to stop using their cars.
It would spell catastrpohe for the UK budget. Thats why the price of transport via bus or train is rising rapidly. They are fleecing those now fiscally compelled to travel by 'public transport'. Most of what we pay in taxation as motorists is paying for a bloody great raft of NHS improvements and new schools. Luckily for us these have been largely commissioned through PFI. Which means they are more expensive and give less service than if they had been left in the public sector. They are put through as PFIs because they are then 'off the books'. that is they are not included as debt/liability in the budget. Cyclops has been doing this for a decade in the name of 'prudence' (sic). So we now have something approaching half a trillion of debt to private companies whose first priority is to make a profit NOT provide a service. This debt still has to be serviced.
This is sort of reason why you cannot expect any respite in tax burden. In fact the likelihood is that taxation, both direct and indirect, will increase significantly. It has to because it looks like our mighty leader has screwed the whole bloody country with his sub prime behaviour at the exchequer.
Gordon Brown wants you to drive your car. A lot.
