World War I changed America, or at least hastened the pace of change. Some of these changes might have been good, but there was a sinister side to some of what was going on as well.
Affects for US Women
On the negative side, inflation was high and companies and corporations started the reduce wages and lay off workers to keep down operating costs.
Effects for US Immigrants
By that time, anarchism also established itself around the country while socialists of different tendencies were involved in early American labor organizations and struggles which reached a high point in the Haymarket affair in Chicago
Effects for African-Americans
Large numbers of women were recruited into jobs vacated by men who had gone to fight in the war.
Concerns over mass immigration and its impact on the country began to change Americans’ historically open attitude toward immigration.
African American citizens saw an opportunity to win the respect of their white neighbors.
