Because Beneatha is the most educated of the Youngers, she sometimes seems to be obnoxious and self-centered; especially in the early scenes, she freely verbalizes her views in a household that has difficulty understanding her perspectives. She favors her African suitor over her rich boyfriend, much to the puzzlement of her family.
Even though her family is clearly poor, Beneatha has no reservations about feeding her ego. We learn that she "flits" from one expensive hobby to another as her mood dictates, even though it often seems that the family could use the money spent on Beneatha's horseback riding, her camera equipment, her acting lessons, and her guitar lessons for other, more financially relevant things.
