What happened to personal income between the years 1921 and 1922

After five years of very high tax rates, rates were cut sharply under the Revenue Acts of 1921, 1924, and 1926. The combined top marginal normal and surtax rate fell from 73 percent to 58 percent in 1922, and then to 50 percent in 1923 (income over $200,000).
