Opinion on Economic Boom Statement

'Without the new automobile industry, the prosperity of the 1920s would scarcely have been possible.'

I agree with the historian to some extent because the automobile industry was not the only factor that was really important, but still was definitely one of the biggest factors leading to the prosperity of the 1920s. Sources that agree with the historian are Source 15 and 16. Mainly these prove this statement to be true because Source 15 shows how much the development of industry had improved and proves that jobs were provided because of the number of automobiles that were being bought and the demand for them. Source 16 proves that cars were very important to Americans and were a huge demand in America. As seen in the picture, multiple people had a car and the statistic that goes along with this is for every one car there were 5 people which was a lot more compared to around the world. The source that disagrees with this historian is Source 12 which shows how much trusts had an impact on everyone in America, especially the people with power. It provided multiple more people to become wealthy than previously were (which is also shown in Source 11) and that led to a huge boom of people becoming more prosperous.
