Something like this would work with some sort of work-school program so long as the person learning is getting paid a fair wage while working (% of the learned person's salary, increasing as time goes on). But I feel trying to sell this sort of thing to businesses so this is the norm is going to be difficult. So sure, if someone can get this sort of thing, go for it.

But we still need the schooling option. For folks that want to start a business themselves. for folks that are getting other sorts of experiences while they are young. People wanting to continue schooling. And so on.
