I have a bachelor's degree in political science. I went into the field because I wanted to help people, and by the time I had completed my degree I had concluded that there was no way to do that in any meaningful fashion by working with politicians. Maybe I'm just being too cynical, but nearly every political official in our government has too wide an ideological gulf separating them from my own views for me to be able to tolerate working with them, both on the authoritarian/libertarian and on the economic scale. And there's no chance I can get elected to anything significant, with my social and (somewhat anti-) religious views. To be honest I'm not sure an atheist could get elected dog catcher in this country.
I'm still hoping that I can make some meaningful changes outside of the system, but we'll see. For now I'm just working at a book store whilst I recuperate from motivational depletion due to six years of university. (Yes I switched majors a lot).
