Ludlow Massacre

In my literature class the other day, we were discussing labor history in the United States. We were reading "South of the Slot" by Jack London, and a group was presenting on The Jungle by Upton Sinclair. It quickly became very apparent that not many people had heard of the Ludlow Massacre that took place in Ludlow, Colorado in the early 1900's. I think it is interesting that no public schools in Colorado discuss what occured during the largest labor conflict in US history. Fortunately enough, my grandfather took me to the memorial site when I was fairly young, and explained to me how tent colonies were set up by the Rockefellers in order to increase coal production, and decrease mining costs. He also explained to me how scrip was used to create a dependence amoung the workers. My family has always been very involved in labor unions, and I thought that was fairly normal amoung working class families in Colorado. However, I am becoming more and more aware of the negative "implications" unions have amoung citizens in this state. Here is the site in case you are at all intersted in why unions exist, what they have done for workers' rights, and Colorado history in general. http://en.wikipedia.org/wiki/Ludlow_massacre
