If the work I do does not contribute to this society then neither does yours or anyone else who teaches English here. I pay taxes, that is contributing to this society. I teach people how to speak a useful 2nd language again contributing to this society. One thing that is not contributing to anything however are people posting up factless statements and just spoling for a fight with someone online because they have a different opinion. Some of you would have done well in Nazi Germany, another group of people who tended to believe their own BS and attack anyone who disagreed without debate.
