The result of the research that mister Wilders wanted to carry out: the reintroduction of the guilder is more advantageous than the preservation of the euro. After ten years the elderly amongst us have finally gotten used to that wacky euro. They used to give their grandchildren a knaak for a good report, now that has turned into €2,-. Those grandchildren made some profit on the change. At the same time those grandchildren have never seen a knaak up close. Does this mean we have to teach this new generation words like knaak, joet and geeltje again?
