In late 1800s, in United States, the B. growth of middle class was changing.

Though the industrialization was on the verge of prosperity in the late 1800s, 'mass-production' of goods was not yet being done. More people started to get employed and thus the leisure time that the people had earlier decreased considerably.

Though the societies modernized, blacks and minorities were not given the importance they deserved as humans. Because there was a growth in the rate of employment, poor families experienced prosperity and grew to become middle class families.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
