They prefer newby (ignorant), non-native English Europeans who they can pass off as American. All incentives are based on fines for all kinds of reasons so expect your salary to be cut into each month.

That rings true. They are training students to be understood by Poles and the like. And the poor students are told that their teachers are American. The American accent seems easier to forge or something. I have heard actually of students telling their Brit teachers that they couldn't understand their accents because their normal teachers are American. Or so they think!! More likely Russian.
