No; cynicism is intellectual and moral laziness. It allows you to distill a complex world to a simplified negative caricature that justifies not making an effort yourself (or makes your efforts seem more extraordinary than warranted).
My personal counter anecdote: 2 weeks ago, I lost my camera (with a nice new lens on it) in the subway. Worth more than $700. Everyone I told said almost the same thing: "you'll never see it again, someone would have to be stupid to give it back; I would, but I'm stupid."
Well, 2 days later I picked it up at the lost&found.
