Indeed, the 1920s left America with jazz music, flappers, The Great Gatsby and an era of good fortune, there was much more to this era than the optimism and enthusiasm. After the end of the Great War, America had hope, which led Americans to take their savings out from under their mattresses and invest in the stock market which soared throughout the 1920s , leading to an economic boom. Although the 1920s remind us of a period of prosperity in American history with some of the most important inventions, we fail to remember what led to that era and its downfall. We tend to think of technology as useful and promising, but new inventions have left half of America in the past and the other pushed toward the modern world. New laws enforced by the government gave rise to gangs and the black market. The Roaring Twenties thrived on technology and changed the economy, social roles and culture. Along with prosperity and optimism, Europe has influenced our society and this era has had many negative results. Various inventions from the 1920s have impacted the world of technology and the world as we know it today. The Model T Ford was invented in 1908 and was originally only purchased by the wealthy. The Model T was sleek and attractive, unlike older car models. After the war, when prices fell, production boomed because ordinary people could afford to buy them. The Model T assembly line gave many Americans seeking employment after the war a work opportunity. Not only were sixteen million Model Ts sold in 1927, but the popularity of the automobile led to the construction of more roads and highways with public funds. Because more roads were built, more people went to cities to find work, which impacted the economy. Many talk about the Great Depression which lasted ten years and ended at the start of World War II. The twenties are associated with wealth, extravagance and optimism. After the successes of the war and the economic boom, everyone was optimistic. Immigrants from Europe came to America because it soon became known as “the land of opportunity and wealth.” The luxurious and posh lifestyle of socialites was known to resemble the lifestyle of the English royal family. American socialites took advantage of this because we were a democracy and to be a socialite you had to have money, not have inherited power. American women were able to marry into European royal families despite having no title because they had a lot of money. Although many thought the good fortune would last forever, it collapsed in 1929, ending the most extravagant and optimistic era in U.S. history..
