Trevor showed that food or having access to food was what determined whether a person's life would be good.
We can arrive at this answer because:
Trevor shows how his mother tried to make sure he had food.
She made money with a lot of effort to get him to have good food and access to books.
According to him, having food, or having access to food was proof that one's life would have good things, good status, and prosperity.
This is because the people who were able to eat correctly in that region were the ones who had enough energy to pursue their goals and conquer their desires.
The above question is related to the book "Born a Crime," where Trevor Noah shows how he went to live as a mixed-race child in South Africa during apartheid.
