The elephant in the room is how long will be it till unemployed and underemployed workers start to vote for outright Socialists(under the D label of course)? No one knows when this will reach critical mass, but combine these displaced workers with easily minipulated 3rd world immigrants as voters, and I fear we are headed to a full on social welfare state that will make the Great Society pale in comparison.
What a useless argument, especially since the position most protectionists take favors more state intervention. So in other words, "You fear socialism? We must try socialism!" What a joke.
