No - this is a raise in the form of subsidized education, and it's hard to see how that's worse. I'm very dependent on my employer because I live off of my salary, but that doesn't make it a dystopia. If they wanted me to learn X, and paid for my training in X, I may not enjoy that as much as the cash value of the training but it's still a benefit to me. For Wal-Mart, the employee can leave whenever, they will either forfeit their incomplete program or graduate and now have a degree.
This is literally the classic CFO/CEO exchange:
CFO asks CEO: What happens if we spend money training our people and then they leave?
CEO: What happens if we don't and they stay?
