"a democratic soverignty" AKA a dictatorship , a benign one perhaps, but a dictatorship none the less.
As for the high cost of fuel - there is undoubtedly a political element here. 70% , yes 70% of the cost of a litre of road fuel goes directly to the government in the form of duty and VAT ( at tax on a tax! ). It has risen to this disgusting level due to the effects of the fuel tax escalator put in place by the last Tory chancellor, and continued by 'Macbeth' Brown.
As for the ***** Thatcher - I believe that the Death penalty is still on the statute books for treason. In her destruction of the Trade Union movement through the removal of jobs, she made sure that there was no opportunity for mining to resume EVER again by ordering that the mines be not mothballed, but abandoned, thereby ensuring that the vast reserves of coal beneath Britain remain there - probably for all time. So What? So what is that the technology now exists (and has done for some time) to make oil from coal. When oil reached $80 a barrel, the process became economically viable, but only if the coal was locally available. Transport costs on top tipped the balance.
Thatcher did much that was good and needed, but like all dictators lost her head to the power with which she was vested.
Not only were mining jobs destroyed, but much of our manufacturing was exported to the Far East. We were told at the time, that we would find plenty of work in the Service and Finance Sectors. Now we find those opportunities going to off shore call centers as well
