Ask for a masterpiece about an American family who immigrated to the west by carriage.

Grapes of Wrath is based on the bankruptcy, famine and struggle of farmers in central States during the economic crisis. Farmers in Oklahoma and neighboring Texas, Kansas and Arkansas were heavily in debt. Their land was confiscated by big companies and they were homeless, so they had to move west to find a way out in California. [ 1]

The novel, represented by Mr. and Mrs. Childers, tells the difficult experience of twelve of them fleeing from Oklahoma to California. After they sold everything in the family, they got an old car and the family fled to the west by car. On the way, young Noah and Connie gave up halfway. When I arrived in California, everything was not as beautiful as I thought. What awaits them is still unemployment, hunger and hardship. Farmers there use surplus labor to depress the wages of tenants, and local forces extort and persecute wandering farmers. So the farmers became angry, and they United to resist. The "Anger" in The Grapes of Wrath is a strong protest against the unfair social system that leads to people's poverty.
