No Leftist slant in this film

I don't want to see any posts here from the tea party right that this is a "leftist film". This a movie about a tragedy that should have never happened and if not for the labor movement could have happened again. With the attacks on labor unions in the news , let's all pause to remember the poor souls who perished due to greed and the slowness of the goverment to institute safe-guards in the work-place.
