From the handful grads that I know and from the advice of professors I've talked to... being involved in your academic passion is more important than the goal of a job. The former can lead to the latter. The people I know that volunteered or sought internships or got involved in clubs related to their field got good jobs. The people that just got a degree so they could get a job in something they are somewhat interested in are still making min wage. That doesn't mean that ALWAYS happens or that the latter is screwed forever, but what the former group did really helped them succeed in the working world.

If you are really passionate about something you should stick with it, because that passion will shine through and make you stand out among other applicants. It will also help you be tenacious in the tough times...
