I am fascinated by the study of the use of scare resources which have alternative uses. Further, I’m frustrated by the fact that I shrugged off Economics while I was going to college. Instead, I focused on engineering and math, physics and chemistry. In retrospect, how boring and useless ;-).
But the idea that all things have alternate uses is fascinating. And critical. Combine this with the fact that all people will pursue their individual self-interests and you will find the decisions people make to be interesting as well.
And it’s within this light that I judge and critique government policy.
