I've thought about doing this at work, but it's hard to figure out how to make it attractive to my company. If I ask to hire a junior dev for the primary purpose of training them, it seems likely that I could get them full time for 50% of my salary. They're going to be a little bit productive, but they're also going to take up a lot of my time. At best, I think you end up with 150% of the labor costs for the exact same amount of work being done. That's a really hard sell to the business side of the company.
