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).

what the question i might be able to

native american contribution: the patriots from britain learn how to hunt, fish, and introduce diversity within cultures.

african americans: indirectly introduced the idea of diversity to americans. africans coming to america because of slavery taught white americans that people come from different backgrounds and colors. it also built america's economic stability for a great period of time. 

women: make america what it is today. there are some societies that are in the world currently that do not give women the same right we give women here in the united states. because women have rights here in the united states, other countries' citizens strive to come to america, especially women, since they have equal rights in the united states. this is important because america is seen and desired by many in the world. 

children: children are our future. we learn from our elders and carry out things the same or differently learning from america's history. we continue tradition and change tradition if it is needed.
