Describe some of the challenges facing the american people during the late 20th and early 21st centuries

The growing trend of Globalization in the 20th century has made corporations shift their means of production to geographic locations that offer lower costs in regards to labor and materials. This has caused numerous manufacturing jobs which were located in the United States to shut down, meaning that hundreds of people were laid off from their jobs.

Manufacturing jobs were one of the main sources of income for the middle classes. These people are now forced to enter jobs in the services industry which offers jobs with lower pay, resulting in overall growth in the inequality gap regarding the distribution of wealth in the country.

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.
