In most cases, the degree is required not by the schools, but by the government. You won't get a visa without one, you won't get a teacher's licence without one, and you won't get a work permit without one. There are some rare exceptions, even in Thailand for example, but generally to be caught working there without those three bit of paper means immediate deportation, perhaps following a few days in the holding pen at the immigration jail. It does happen, but fortunately it's rare.
