I think they were more so arguing about the costs of the training itself. Those loans aren't free for a lot of people, and scholarships aren't unlimited.

A lot of people don't have time to work while they're in school, so those loans can also take on a pretty nasty interest rate.

I'm of the mindset that people who work hard deserve good money. If a job is something that most people can't or won't do, companies will usually have to pay more to encourage people to stay and do those jobs. Otherwise, why would people go into debt for schooling and training? Why go through the stress and expenses for no reason? Yes there's passion for some people, but that doesn't pay tuition lol
