The 'merry-go-round' of finding the cheaper prices, food, petrol and other goods is almost, if it weren't serious quite funny! Belgians and now the Germans are flocking to France because the petrol is cheaper. A little while ago the French were going to Germany because goods and food was cheaper; I go into Spain, as I live in the Pays Basque, regularly for cheaper fuel and food along with thousands of French. In fact, you are hard pushed to find a Spaniard in many of these frontier shopping centres. Even the workers are French!
The day of reckoning will come that's for sure. Subsidies sound great, ask any socialist, but eventually they have to be paid for. It's the economics of the lunatic to continually subsidise to appease the masses!
