The inventions of the 1920s made life much better for the average person. More affordable things meant more people were buying it, meaning more of the product had to be made, meaning more job positions had to be filled. People had jobs, money, and a higher quality of life because of these inventions. These inventions didn't only affect that time period though, it affected the years to come as well. These inventions grew as time went on, and as the inventions grew, society grew alongside it, leading up to the point, what we now call, the "present".
