An Alternative Theory of Unions

Just read the Paul Graham essay
An Alternative Theory of Unions.

It is a great read. Last month me and others argued about unions in a post in broken toys. One side of the argument is unions protect workers, and my argument is unions will prefer manu work in farms and resist machinery. The essay supported my argument from another point of view.

Of course, that essay also give me chills. I have long believed that one day IT work will be paid less than janitors (IT job is easy and fun). Now I really need to find what is the next high in demand profession and try to switch.
