e. aggregate demand to decrease

Explanation:

A decline in U.S. wealth would tend to cause aggregate demand to decrease. Demand is defined as the amount of goods and services that one can buy at a certain price and at a given time.

When an economy is made up of wealthy individuals, the aggregate demand for that economy tends to increase due to the fact that such individuals have the purchasing power and hence can afford to buy whatever they want.

When there's a reduction in wealth, this will result into a reduction in aggregate demand as the people won't have much fund to make purchases like before.
