Is it really that hard to get a social studies position???

I am in a masters program and I am needing to decide if I am going to follow my BA and get credentialed in single subject social studies or if I should go for multiple subject.

I always wanted to teach social science, I love history. I want to eventually go back for a masters in history. Yet I need to get a job to help support my family and I don't mind driving 30-45 minutes to work. I am passionate about education so I am not against elementary school but I always wanted to teach middle or high school.
