Answer: Russian workers lacked avenues of protest, while American workers had labor unions and political parties.
Step-by-step explanation:
Russian workers in the late 19th century did not have a lot of avenues to protest because they were under an autocratic emperor known as the Tsar and the nobles and upper classes controlled the economy with a tight grip. They were therefore unable to declare their support for Socialism even if they supported it.
This was in sharp contrast to the freedom enjoyed by the Americans when they protested as they were in a democracy and had labor unions and political parties through which they could make their voices heard and champion their cause.
