According to zinn, why did the government and Pullman car company have to conspire in order to defeat the striking Pullman workers?

Howard Zinn reflected on the events that occurred during the Pullman Railway Strike of 1894. Workers from the Pullman Railway Company sought to join the American Railway Union, as they saw themselves harshly affected by the wage cuts the company had put in effect. After hearing the workers' complaints, the Union decided to enter on a nationwide strike, which included the cease of use of any type of Pullman car. The strike was highly effective and in little time there were hundreds of Pullman cars stranded on the railways throughout the country.

The judicial system executed a court injunction against blocking trains. However, this was widely disregarded by the union workers. As a response to this, President Cleveland ordered troops to go to Chicago and suppress all of the violent acts. As a result, 30 workers ended up dead during struggles with the soldiers. Zinn proposed that the actions of the government were orchestrated along with the Pullman Company, as it operated in an industry that was critical for the country's economy and could not be stopped.
