But, as one that has studied economics as a discipline - like I have at the undergraduate level and through separate book reading - that is exactly how I view myself...a labor unit with a price tag that can, and will, change abruptly with the conditions of the market for the knowledge, skills, and abilities that I can bring to the table. I know you don't believe this about me but I am being quite serious and genuine here.
The problem with companies treating employees like disposables -- which is what you're essentially saying that people should accept -- is that people tend to put a lot of themselves into their work, not to mention basing a lot of their financial decisions on the assumption that their job is "theirs." In a "faceless capitalism" scenario, the company's stake is far different than that of its employees.
As such, the natural response to something like outsourcing is resentment, and resentment breeds a variety of unwanted results, especially political ones. It's all very well to say that people shouldn't think that way, but the fact is that people do think that way.
