Common sense isn’t always right. It is difficult not to agree with protestors at a giant oil refinery yesterday. “We have a growing problem in the engineering and construction industry where UK workers are being excluded from important projects. The Government must take urgent action to deal with this situation as tensions are reaching boiling point,” said Derek Simpson, joint leader of Unite. And across the land, people munching on their breakfast, or driving to work, nod their heads in agreement. It is ludicrous to recruit workers from abroad, when there are British workers who can do the job just as well. Gordon Brown called for “British jobs for British workers,” and yesterday, protestors echoed that call. It is just that we are seeing the thin end of a wedge. We are now entering the most dangerous phase in the credit crunch. Governments across the world are now faced with conceivably their most important challenge. It is vital that the other side of the argument is put forward, or else the credit crunch really will degenerate into a full scale depression.
