Not all company are deemed to be unicorn. You know, you could just try to create a decent business bringing decent income, and beginning by exchanging what you know to students / young adults / dropped out is a good start if you like that path. I would certainly do it if I find the right people to train, and I would have loved it to have a serious mentor earlier in my life in this way. No one here can judge or make decision for others there's so much things in life that to pretend otherwise seems silly.

EDIT : actually, now that I think of it, I know a friend who did exactly that. He even said to me that he preferred this unpaid internship to the one he got one year later, paid, but bad environment and no mentorship.
