Why?
Maybe because we are/were/should be again an exporting economy and we have made ourselves very uncompetitive over the last 10 years by giving ourselves pay increases that we didn't earn (by earn I mean increase our productivity). The net result is that goods can be manufactured and services provided in other EU countries t a fraction of the cost here. I currently outsource to the UK at 35% of the unit cost I would pay here.
Jack O'Connor was on the radio last night claiming that pay cuts are not the answer and would in fact damage the economy. He said that no economy was helped by reducing their costs. The guy from ISME was utterly useless and let him away with that rubbish. Anyone who knows anything about the German economy for the last 20 years could blow his argument out of the water.
Listening to socialists talk about economics is like listening to fundamentalist creationists talk about evolution.
