Job Security for Public School Teachers?

My school district asked its teachers to read "The World Is Flat," by Thomas Friedman, which, while not directly about e-Learning, it talks about the ever-increasing globalization of not only corporations but more directly, the educational system. The premise of the book is that the playing field of world economics and opportunity is being made flatter by the Internet, workflow software, outsourcing and opensourcing of jobs and other factors that I didn't find important to include in this blog entry. The point of reading it as a school district is to open the eyes of its teachers to dramatic changes our students must be equipped to deal with as well as teachers realizing that our "cushy" and tenured jobs are not as steadfast as once thought. For those of you with alot of time to kill (you could use this book to block your car's tires), it goes into several concepts we have looked at in this class--wikis, blogs, and other software--that allows training, instruction, and work to be done at great distances and how those tools are creating more opportunities for whole populations of the world that could never keep up with countries like the United States in global economics. I would include the link to the author's site, but currently it is not up and running, but I think this book helped to solidify the importance of alot of the concepts we've discussed so far in this class.
