What types of social inequality are found in The Pearl by John Steinback? Use quotes to support your answer.

We see class inequality from the very beginning of the story. Kino and Juana live in a small hut with their baby, but they seem happy. This happiness ends when Coyotito is stung by a scorpion. A crowd gathers, and the family passes on the message that someone should go get the doctor. However, it is passed back that the doctor will not come.

A wonderful thing, a memorable thing, to want the doctor. To get him would be a remarkable thing. The doctor never came to the cluster of brush houses. Why should he, when he had more than he could do to take care of the rich people who lived in the stone and plaster houses of the town.

Kino and Juana are limited by their money and limited by where they live. There is only one doctor. He is described as "fat" and "lazy," and the four beggars know of "his ignorance, his cruelty, his avarice, his appetites, his sins." Although the story is focused on Kino, these four beggars also highlight the financial inequality present in the story.
The description of the doctor's house is a huge contrast to the description of Kino's home, which shows the inequality. The doctor refuses to treat the baby because Kino has no money.
The doctor also highlights racial inequality.

This doctor was not of his people. This doctor was of a race which for nearly four hundred years had beaten and starved and robbed and despised Kino's race, and frightened it too . . . all of the doctor's race spoke to all of Kino's race as though they were simple animals.

The doctor then demonstrates this attitude when he tells his servant "Have I nothing better to do than cure insect bites for 'little Indians'? I am a doctor, not a veterinary." By saying he is not a veterinary, he is calling Coytito an animal.
After being turned away by the doctor, Kino goes pearl diving to find payment. When he holds the Pearl of the World, he dreams of marrying his wife in a church, owning a rifle, and giving Coytito an education. These dreams showcase the inequality in his life. Coytito would not have access to education without the money.
After hearing about the pearl, the doctor comes to Kino's hut to treat Coytito. The doctor says he will return in an hour. Again, Steinbeck's rich descriptions highlight the inequality; the doctor eats a rich meal while Kino worries about his son.
Another example of social inequality is gender inequality. Juana does the housework, but it is clear that Kino is the sole decision maker. Although Juana warns him against the pearl, he does not listen. He even beats her at one point.
