If you're only trading time for money in your career, IMHO, you don't have a career, you only have a job.
At the least you should also be trading your time for expertise, networking, and accomplishment, although I would also recommend some degree of self-actualization and everyday enjoyment (if you're in a position to seek for those).
This ties back really well to the OP. The most important thing in interviewing is dividing people into these two categories. 10 years of experience clocking-in and clocking-out is no experience at all. I'll hire some kid who is a go-getter over that.
Unfortunately in academia it only matters if you hit your grades, which are gamed to hell and back. So you really can't tell at a glance if an A student is going to be good or bad, I hired based on a transcript once and got burned so badly that I'll never do it again.
