Response to 'Mayday'

After reading up about Mayday, and hearing Andy's short version in class, i thought it was silly of how they came up with Laborday. As Andy compared it, to Mayday, a day where people would rome the streets with they're fists in the air for something that is seen as a huge accomplishment towards the average worker, to Laborday, a day where people celebrate a three day weekend with barbeques and days spent at home or ordering out for lunch and dinner. The event that occured in 1915 celebrating Mayday is remembered and mourned rather then celebrated to this day in other countries Except the one in which the event had occured in. i think thats very interesting and for that to happen so close and near times where people in New York and other places were becoming victims of unemployment. Only question is why were there police present at a rally that has been happening for the last 20 years then. If no incidents had occured then why show after? if my research is correct that is...
