A long time ago there ware 4 simple roles a farmer, hunter or gatherer and solider all of which ware needed for basic survival. Then there was a revolution and these basic jobs became more and more unpopular and new jobs ware appearing through new discoveries. Now to make a simple meal we don't need to be a farmer and know hunter and gatherer we just go to store buy it and cook it. What is productivity? Productivity is a number of products made by a single person or bigger communities like country in certain amount of time. What that basically means is that we spend less time to produce. You might say this degrades the quality of products but it certainly increases each individual efficiency.

The African Americans in the roaring 20s were treated unfairly and badly. Slavery was a problem in the 20s and African Americans were kicked out of their homes and lost jobs. Many African Americans worked on plantations and were living in harsh conditions. Immigrants also worked on plantations and were refused many jobs due to their background. Many immigrants had a hard time finding jobs and being able to support their family. The stock market crash made it harder for immigrants and African Americans to live. More people were kicked out of their homes due to the stock market crash and many people lost their lives because they were poor and did not have the funds to support their families.
