In my opinion the problem you're describing (people leaving after getting up to speed) has more to do with the HR department controlling salaries. If you get a bit of experience under your belt, and get good at what you do, you've got to switch companies to get a raise that reflects your new level of expertise. There are some companies that will raise your compensation to reflect your experience, but most won't. And that's the problem. On the other hand, not training your team costs a whole lot more!
