If the Finance Minister could realize what a source of income to the state my buildings will be in fifty years! Remember what happened with Ludwig II. Everyone said he was mad because of the cost of his palaces. But today? Most tourists go to upper Bavaria solely to see them. The entrance fees alone have long since paid for the building costs. Don't you agree? The whole world will come to Berlin to see our buildings. All we need to do is tell the Americans how much the Great Hall cost. Maybe we'll exaggerate a bit and say a billion and a half instead of a billion. Then they'll be wild to see the most expensive building in the world.
