Fuck grad school. You're just putting off learning something useful. Learn you the basics of some trade you like - programming, plumbing, piñata making, what have you - and apply for jobs. Network.
That's quite subjective. Most past figures who's contributions to society I would deem useful, who have fundamentally changed our lives and the ways we think, have been well educated. Yes, grad school is probably not the path the maximum monetary wealth but there are greater glories.
In fact, I'm going to school to learn a trade -- counseling psychology. It's a prerequisite to being licensed.
The question now is how do I earn while in progress toward that goal.
