Write a summary of the following text. A goldsmith set to work on a gilded cage. It turned out to be of such exquisite workmanship that people from far and near crowded round for a look. Some said, "This is education par excellence." Others said, "Even if it learns nothing, it has got the cage. What a lucky bird." The goldsmith was delighted to get a bagful of money as reward and went home at once. A teacher came to give lessons to the bird. He took a pinch of snuff and declared, "This isn't a matter of just a few texts." One of the royal nephews sent for scribes. They made multiple copies of various texts until there was a veritable mountain. "Bravo!" exclaimed those who saw it. "There is no room for any more knowledge." The scribes loaded their wages onto bullocks and merrily headed home. They would never want for anything .The nephews were constantly busy looking after the expensive cage. Repairs were always under way. Anyone who saw the endless dusting, wiping and polishing had to agree that there was "marked improvement". A large maintenance crew was needed, and more personnel to supervise them. They all got handsome monthly salaries, which they saved in their wooden chests. Even their cousins came to live with them in cushioned comfort.
