Even before 1929, people working in the agricultural sector (they had jobs such as vets, farmer, labourers, clerks) had trouble to keep theirselves financially stable due to the rising competition of the economy. Thus, many small farms and firms had to shut down. Technology increased in supply, but the demand of food was not going at the same rate. The day wall street crashed, the prices fell and farmers' incomes dropped. This made it much more difficult for them to find jobs in the economy, let alone the middle-class people.
