Here's why:
* Bob Ewell was a drunkard: His alcoholism made him unreliable and irresponsible.
* He didn't value education: Bob Ewell saw no point in educating his children and believed it was a waste of time.
* He was prejudiced: He held deep racist and classist beliefs and didn't want his children to associate with people of color or those from different social classes.
Burris Ewell's infrequent school attendance highlights the stark contrast between the Ewells' impoverished and neglected lives, compared to the other children in Maycomb, Alabama.
It's important to note that the Ewells were not the only ones who faced challenges in accessing education in Maycomb. Poverty and racism played a significant role in limiting educational opportunities for many children, particularly those from Black families.
