the majority of Americans didn't want more soldiers dying in foreign wars thousands of miles away. they were afraid of massive cost and future wars, and foreign people coming into the US, which was why acts were passed, such as the Immigrants Quota Act of 1921. Americans did not want immigrants to take jobs because wages were lower since the immigrants would not join labor unions; they accepted lower wages. Americans also feared immigrants because of WW1 and the new political ideas they brought.
