How did the 1920s
affect various social groups in the United
States?

Explanation:

It affected the various social groups by (putting this very bluntly) making the upper class richer, making more room for a middle class society to grow as well as the suburbs, and it slowly withered away the poorer class of society. All of this would change of course after the Stock Market Crash in 1929.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
