There are so many new bio PhDs minted every year that the labor supply is far out-pacing demand. Right now, the big names (I'm lookin' at you, Genentech...) are hiring extremely talented people into glorified lab-tech positions.
In short, biotech is no panacea.
If you want a science field where demand far outpaces supply, try geology, with an eye toward either oil or mining. In the oil industry, there are 30,000 qualified geologists to fill 90,000 jobs. My sister's salary offer jumped $10K in the year she delayed entry into the workforce.
She also says that there's a huge software opportunity in geology, because existing software sucks. However, you need some pretty specialized domain knowledge, and you'll be competing against Schlumberger and Halliburton. That's great for technical superiority, but you'll probably have difficulty breaking into Halliburton's old-boy network.
A good approach to starting a business in this space is to pick your target audience, and find out if your team can easily fix any of their biggest problems. If not, iterate to a different target audience until you find a good problem for your team.
In the medical device realm, I know of a couple groups of undergrads that have developed technologies that attracted VC attention. Titles and credentials are not deal breaking obstacles.
