Final answer:
The correct answer is option C. The incorrect statement about the distribution of income and wealth in the United States is that the share of money income received by the lowest quintile has increased significantly since World War II.
Step-by-step explanation:
The distribution of income and wealth in the United States can be analyzed using tools such as quintile measurements and the Lorenz curve. When examining these measurements, we find that the statement "The share of money income received by the lowest quintile has increased significantly since World War II" is not correct.
Data from the Federal Reserve Bank's Survey of Consumer Finance show that the distribution of wealth is unequal, with significant gaps between the highest and lowest quintiles.
When evaluating statements about the United States' income and wealth distribution, we should remember that while the middle class may have access to pension plans, the distribution of wealth at the top is more concentrated. The Lorenz curve demonstrates that the United States is far from perfect income equality. Therefore, statement C is incorrect because it claims an increase in the lowest quintile's share of income since World War II, which has not occurred to a significant extent.
