You're not going to find plentiful jobs in biotech. And starting up a new company is nowhere near as easy as it is in tech. I know almost no one from school that got into it. The one person I do know is working on genomic sequencing for race horses..
I hate to say it, but it really needs steady/consistent government funding - both training students and supporting companies. We could be way further along in biotech overall if there were actually a good number of us working on it. No sane investor is going to put money into R&D that will end up failing 9/10 times. And even if you hit on something, the healthcare system is so jacked, recouping your costs are just as hard as developing the product.
