gh, the 1920s became known as the prosperity decade because consumerism escalated so much. It should be no surprise that ethnics participated in mass consumerism. After all, they were the mass production workers that made mass consumerism possible.Stores were a significant part of consumerism, and they helped create a mass culture. Just like the banks, the stores became central institutions that kept ethnic bonds growing throughout communities (Cohen, 110).
