The theory of the leisure class / Thorstein Veblen.

In 1841, free-born African American Solomon Northup was offered a job in his hometown of Saratoga Springs, New York. He followed his employers to the job site at Washington, D.C., where he was beaten, drugged, kidnapped, and sold into slavery, eventually ending up on a plantation in Louisiana owned by Edwin Epps. While there, in 1852, Northup befriended Canadian carpenter Samuel Bass, who was at the time doing work for Epps. Secretly, Bass was able to contact Northup's family, who informed New York governor Washington Hunt of his kidnapping. The state was able to use a law passed in 1840 that allowed the recovery of free black men who were sold into slavery to rescue Northup. Solomon was finally made free again on January 4, 1853. One of few slaves of his era ever to regain freedom, he devoted his time and energy to lecturing and educating others about abolitionism. His memoir of the experience, Twelve Years a Slave, was published in 1853, during his first year back as a free man. Twelve Years a Slave, a best-seller in its time, became a major motion picture with an all-star cast in October 2013, starring Chiwetel Ejiofor as Solomon Northup, Brad Pitt as Samuel Bass, and Michael Fassbender as Edwin Epps. Cosimo Classics is now presenting a paperback and hard cover jacketed republication of the original edition.
