Answer: The Automobile industry
Explanation:
In the 1920s, the Automobile industry had been revolutionized in no small part by Henry Ford which led to cars becoming so popular that everyone wanted to buy one.
This growth in the automobile industry led to growth in other industries that the automobile relied on such as oil which powered the car, glass which was used to make the cars, tourism which became easier to engage in with a car and road building which provided a conduit for cars to move.
Civil Rights Movement was caused by the rampant discrimination of the segregation laws that had continued in the USA.
Explanation:
Segreagation laws were an arachaic practice that had continued in the USA even as the world was rapidly decolonizing and becoming increasingly free among its people.
Many countries had already achieved universal suffrage but USA was far behind in this thing from the other countrysides of the world
Thus the leaders felt that there was a need for revolution to bring constitutional equality to USA that it has always talked about in its constitution but never actually practiced in real.
