Actually the quickest and easiest way to lower prices, without affecting the minimum wage (Already rather low), is to simply reduce the ridiculous tax burden on the average British consumer. People are taxed when they are paid, taxed when they purchase, and taxed when they save. If you've got more than a certain amount, you're taxed when you die, too. Petrol duties are such that we have... insane prices at the pumps. Airline taxes, now even higher, are so high that it's not uncommon for half the fare to be tax (Yet we're apparently not taxed enough!) It was for me the last time I went to the US.
