According to your link it was real. "That’s not to say that everything about the story is wrong; merchants really did engage in a frantic tulip trade, and they paid incredibly high prices for some bulbs. And when a number of buyers announced they couldn’t pay the high price previously agreed upon, the market did fall apart and cause a small crisis—but only because it undermined social expectations."
In the link I posted is this gem: "Peter Garber in the 1980s published an academic article on the Tulipmania. First, he notes that tulips are not alone in their meteoric rise: 'a small quantity of ... lily bulbs recently was sold for 1 million guilders ($480,000 at 1987 exchange rates),' demonstrating that even in the modern world, flowers can command extremely high prices."
I wasn't making a point about the degree of societal collapse from tulip mania. I made the point that there is a long history of greed and speculation.
