How Do I Deal With My Parent's Disappointment?

Dear Experts, I graduated this summer with a degree in economics. I did alright in school, but not outstanding. I've been home with my parents since May looking for work, but have yet to land a job. My parents are pretty disappointed in me. My dad even mentioned that he can't believe he spent all that money on my degree and I've got nothing to show for it. Honestly, I've done everything I can to find work, but nobody calls me for interviews. Please give me some suggestions as to what I can do to find a job that will make my parents happy.
