Which best summarizes American economic issues at the end of the 1920s?

By the end of the 1920s, businesses were producing more goods than consumers could buy, creating overproduction. Many people relied on credit to purchase goods, while investors speculated heavily in stocks. After the 1929 crash, widespread bank failures deepened the economic crisis, so “overproduction, too many credit purchases, stock speculation, and bank failures” is the best summary.
