Final answer:
Workers walked out of the Pullman Palace Car Company because Pullman lowered wages and kept rent high during an economic depression.
Step-by-step explanation:
The workers walked out of the Pullman Palace Car Company because Pullman lowered their wages and kept the rent high. In 1894, during an economic depression, Pullman cut employees' wages but refused to lower their rents, which were already higher than those in the surrounding area. This unfair treatment led the workers to go on strike.
