Most restaurants had sepearate entrances for white and colored people. One of the Jim Crow laws was that colored people couldn't dine with white people, without a barrier between them. "It shall be unlawful to conduct a restaurant or other place for the serving of food in the city, at which white and colored people are served in the same room..". They had to have a solid partition, at least seven feet, from the ground up.
Jim Crow made it illegal for white children to be taught in the same environment as African Americans. In some states they were allowed to be in the same building, but in most than had separate schools. White schools received more money than colored schools, and if the town doesn't have enough money to build two schools (black and white) they will just build a white school, and the blacks wouldn't have one. Also, in some states black children weren't allowed to use books that had the Declaration of Independence in it. The whites didn't want to fill their heads with ideas of equality.
The Great Depression
The Great Depression was a hard time in American History, when people couldn't find jobs and the stock market crashed. This took place in the 1920's. This was the beginning of the worst economic depression in U.S. history. The Great Depression hit the South, harder than most other regions of the country. Foreign competition, overproduction, and man-made fabrics, like rayon, led to low demand for cotton in Georgia, which led to cotton prices dropping and putting people out of their jobs. In "Roll of Thunder", the Logan family owns a plantation. This will effect there family greatly, especially because they are African American and treated unfairly.
