It seems astonishing that people are paying large sums of money to obtain master's degrees in anything. If you have no opportunity to get paid as a research assistant / teaching assistant and have tuition covered by some other route, like a grant or something, then it's probably not a real graduate program, just a means of extracting cash from aspiring students.
Real research and teaching programs need graduate students and will offer you a package of some sort if they think you're any good.

If it offers a Master’s degree it’s a real graduate programme. Not being difficult, not covering material that is useful, not being impressive, none of these are disqualifying for being a graduate programme. Education schools exist. Law schools exist. Business schools exist. They’re all graduate programmes.
