60% of my graduating class are still unemployed or not employed fields even remotely close to science/engineering, there are hundreds of linkedin groups filled with engineering graduates searching for work; any work at all.
Then maybe you/they should have looked into what the job prospects would be before they went into that field? I seriously doubt that the market for engineers changed all that significantly in a matter of a few years while you were in school.
Or, maybe you/they need to consider alternate fields. I have worked in a number of different fields, and exactly NONE of them have anything even remotely to do with my degree.
This isn't a matter of running out of ideas, ideas are cheap. This is a matter of literally not having the financial infrastructure for new graduates to even conceive pursuing developing ideas into successful start-ups without having rich parents keep you afloat while you do the pre-angel work.
If you are having trouble surviving, you shouldn't be looking into that kind of crap anyways. Go get a job with an established company, then you can consider thinking about a start-up business many years down the road when you have a lot more experience and savings to drawn on (and/or more established credit history for loans.)
There is simply NO WAY that I believe you couldn't go get any of about a thousand different office-based jobs making 40-50k so why you are working for $11/hr at Wal-Mart is a bit baffling to me.
