Jefferson came to personally know Banneker and recommended him to be on the Washington D. C. Planning committee. How do you think actually meeting Banneker may have changed Jefferson's mind about Blacks and their capabilities? (Clearly Banneker could utter thoughts above plain narration). If you watched (FROM THIS VIDEO LINK) you'll understand this.

Thomas Jefferson was against the idea of slavery, as he believed on the abolition of slavery and equality among the different individuals across the United States and other colonies. As, there were certain laws and principles inside the constitution of the United States which prohibited the country from allowing the Blacks and White Americans to work or even live together in a more equal way.As, made a huge amount of effect on the over all work and life balance of the individuals across the region. While, there were people both from the social and political system that contributed to the abolishment of such inhumane laws and principles that were acting as a big hurdle in the development of the over all society and industries across the region, which would then likely generate more profit for the system itself, as it would help in creating more jobs and other opportunities for the number of individuals.
