After having read all three of the articles that compare liberal, conservative and radical views of labor unions, income distribution and pollution, write a one to two page paper outlining any common threads you feel run through the conservative point of view. Then look and see if there is a common thread that runs through the liberal point of view. Finally look for a common idea that runs through the radical point of view. Also, give your own opinions as to the validity of the arguments. Make certain you back up your opinions. DO NOT SUMMARIZE ARTICLES.
