What are three reasons why reconstruction failed to live up to its potential?

The three reasons why Reconstruction failed to live up to its potential are: 
1. There was a lack of unity in national government. This is because, Reconstruction happened after Americans' Civil War and some of the people in the government didn't like the idea of establishing this which caused the failures of bring the South America into the country, revive the economy and rebuild the broken landscape.
2. Not enough of the freedmen wanted to become free. Although Reconstruction wanted to infuse the freed slaves into the society, it did not successfully established. This was due to the rise of American organizations that made them feel insecure.
3. America could not overcome the issue of racism. 

Fine until slavery ya ya haha
