Throughout the Jim Crow era, presidents, congress, and even the Supreme Court supported white supremacy.
Andrew Johnson, the 17th president of the United States, favored leaving the future of black people in the hands of white southerners. Unfortunately, there was a lope hole in the 14th amendment. It freed and gave citizenship to all black slaves that were born in the United States, so if you were born outside of the United States than that did not apply to you. This is important because the congress made the laws and this law was heavily not favoring the blacks.
During the Jim Jim Crow era, the Congress passed a ton of "laws" that were very racist and unfair towards blacks. One of the "laws" that they implemented was segregation on interstate buses. This meant that blacks and whites could not sit on the same bus or the same part of the bus, or else blacks would be "committing a crime"
There was also a thing called labor contracts. This meant that black people were able to work for white people, but they had to get paid. There were lots of rules for the blacks in order to get paid. The rule also said that the "master" could whip the black worker moderately to discipline them. This was significant because it was almost like a law, but it was still within the Jim Crow topic.
Durning the Jim Crow era, there was an economic struggle that black people had to go through, that especially did not provide black people with the same amount of job opportunities and other opportunities to receive money.
One of my sources is the Thomas Chatmon listening on haiku. This is significant because he was working so hard to earn money. The slave owner took the money that he worked hard for to earn. As you can tell, this could definitely be frustrating. Which makes this situation even more frustrating and unfair for Chatmon is that, the slave owner kept all of the money that he worked hard to make, but if Chatmon tried to make a legitimate case about how he should have the money that the slave owner took then he would be killed(most likely lynched) by the slave owner.
Colored people weren't able to suggest that whites were from a lower social class. If they did then it would be considered a crime. This meant that if a black person had a bigger house and was clearly more wealthy than the white man and the black man told or mentioned it to the white man then the black man would probably be arrested.
Another economic down to the Jim Crow era is that blacks and whites weren't aloud to be sold food or drinks in the same room. If they did then that would be against the Jim Crow "law(s)". This put down the economy because black and whites probably get less customers because only one race could get food/drinks there.
Social and cultural differences made the colored people and white people not get along during the Jim Crow era because people judged people by the color of their skin, and not on the people that they were.
My first source is the George Butterfield listening on haiku. This is bad because the colored person got into an accident and called a white doctor. The white doctor did not get to the hospital on time, so he called the black doctor, but the black doctor didn't want to offend the white doctor, so the black doctor didn't go. When the white doctor finally came he just "checked" the colored person and left him there to die.
Black people were not aloud to engage first with white people in any way or else that would be breaking the law. That would mean that they'd probably be arrested. This was putting blacks down socially because it was making it seem like doing a nice gesture is committing a crime.
In Alabama no nurses were a loud to take care of any black men. This was bad because if a black man is sick than he might die, or get even more sick. That would have been easily avoidable if the nurse just took care of the man(men).
