"There was no doubt that the town respected him and even admired him in a way. But any man who walks in the way of power and property is bound to meet hate." (Pg.48) Joe had power over the town because he controlled everything that happened. At first the towns people trusted and respected him which made it easy for Joe to have control of what goes on.
"And now we'll listen tuh uh few words uh encouragement from Mrs. Mayor Starks"..."Thank yuh fuh yo' compliments, but mah wife don't know nothin' 'bout no speech-makin'. Ah never married her for nothin' lak dat. She's a women and her place is in de home." (Pg.43) Joe does not allow Janie to to make a speech. He says that her place is in the house. You can see from this how Joe controls what Janie does and is allowed to do.
"Ah told you in de very beginnin' dat Ah aimed tuh be uh big voice. You oughta be glad, 'cause dat makes uh big woman outa you." (Pg.46) Joe likes and strives to have power and control over the town and Jaine. He takes advantage of the people of the town to do so. He says that since he is a "big voice" that makes Jaine a "big woman". He tries to make Jaine feel she is as important as him but remains to put himself above her and have the stronger power.
