B. Income dropped 32% for the wealthiest, but just 5% for the middle class.
Explanation:
This was one of the changes that took place during World War II. During the war, the rich lost a very significant percentage of their wealth. This was a consequence of many different phenomena, including the closing down of certain businesses, the loss of consumers and the general slowdown of the economy. However, the middle class was less affected, as they were able to get jobs by collaborating in the war effort.
