It's not a lack of "get-up-and-go" that perpetuates lack of opportunity. "All one needs"? You could gain some insights here by having a few conversations with people doing the sort of precarious contractor work that was mentioned previously. I doubt they're lacking elbow grease.

There's also an implication that it's simply okay to let job security rot away, that people in precarious work should simply read a few blogs and retrain. I'm not convinced that it's a good plan to ignore creepingly pervasive employment insecurity.
