stuart74:The fact you are buying German doesn't matter,
yes it does! Where do the euros to pay for this car come from? How does Britain earn the euros to pay for this import - by selling goods and services to the eurozone. Britain's annual trade deficit with the eurozone is £40bn, of which half is with Germany alone. Using taxpayers' money to boost the deficit with the eurozone and other countries is lunacy.
The rest of what you put is nonsense and illustrates how economically illiterate we have become in falling for the ponzi/pyramid schemes of this venal government and its backers. If the economic slump in the motor sector and the whole economy generally could be solved by boosting purchasing power through taxpayer financed subsidies why not borrow all the time, without limit, or even just print money and hand it out? If what you say is correct this borrowing will eventually pay for itself and more, no?, through some hocus-pocus, voodoo economics. Of course this is madness. Borrowing is what has got the individual and the country into bankruptcy with no prospect of paying off the accumulated personal and government debts. What you're really saying is at base, borrow more to pay off our debts.. Think about it. Keynes was a trifle more spohisticated in his pump-priming defict spending to counteract a slump, but even he would have recommended spending the surpluses gained in expansion years in the recession years not simply borrowing all the time to cover up structural deficts.
The only true way to increase wealth is to dig something valuable out of the ground, grow a crop/raise livestock or transform materials into something of intrinsic worth. Paying people to buy more cars, just as shuffling worthless paper assets around the City of London, does not qualify.
