One of the enduring myths of American folklore is that Jesse James was a home-grown Robin Hood who "stole from the rich and gave to the poor" That legend enjoyed a revived popularity in the 1960s. Supported by movies, pulp fiction, and even serious scholarship, this image has dominated our understanding of the post-Civil War James gang and other western outlaws. Historians have described James as a "primitive rebel" who championed "a special type of peasant protest and rebellion" against modernizing forces by robbing banks and railroads.
But James himself would have considered this notion a great joke. In fact, James’s robbers went after the express company safes just because that’s where the money was. As for the Robin Hood theme, there is no evidence the James gang did anything with the cash they stole except to spend it on fine horseflesh and gambling.
The key to understanding the motives of the James gang—besides
A. people all like the heroes who "stole from the rich and gave to the poor"
B. before 1960 people hardly know the legend about James
C. many peasant rebelled against modernization
D. some literary and artistic works mislead to us about James
