The white man had the power over the black man in the past and there was little that could have been done. In Wright's experience, he says he was always eager to learn and get ahead. However it wasn't just him that the white man oppressed. In a job he had with white men, the boss had instructed the other workers to teach him what they knew about the job. However, they refused to do that and instead accused him of not calling one of the guys sir. They threatened they would beat him and they pressured him to quit his job because they didn't want him there. This is how many of them were oppressed for many years and they had to obey because the law wasn't also on their side. They were forced to respect them even if they didn't deserved to.
I think the right choice was made to rebel against the white man, even if it meant slowly but surely, like for example the Black Panthers who fought for their rights, Rosa Parks being in an organization and refusing to give her seat to a white man, and Martin Luther King being a leader for the civil rights movement. If that hadn't happened imagine still being on those times. Fighting through their struggles for what they believed in was the right thing to do and anybody being oppressed for so long is bound to rebel against their oppressor sooner or later. So in conclusion, these forms of resistance were effective to achieving liberation.
