Goldgar argues that although tulip mania may not have constituted an economic or speculative bubble, it was nonetheless traumatic to the Dutch for other reasons: "Even though the financial crisis affected very few, the shock of tulipmania was considerable. A whole network of values was thrown into doubt." In the 17th century, it was unimaginable to most people that something as common as a flower could be worth so much more money than most people earned in a year. The idea that the prices of flowers that grow only in the summer could fluctuate so wildly in the winter, threw into chaos the very understanding of "value".
