Answer :
Under President Coolidge, the national economy boomed! Coolidge favored policies that aided the growth of business
Under Coolidge the economy was great or boomed as the person above me said. Under his presidency the economy continued to grow and when the economy is great, inflation decreases, which means you can get more for your dollar. It was an era in which one would want to live in, economically speaking.
Hopefully this helped and good luck.
