This piece of history was so critically important to the lives of working men and women ever since that time that almost every nation on Earth, the United States of America alone excepted, celebrates its laboring population on the first of May. I feel that we here on the Anti-Capitalist Meetup and related Groups here on Daily Kos need to remember what happened on that fateful May evening in 1886, and the heroes who sacrificed their lives so that their fellow workers might have access to reasonable working and living conditions.
