Addendum.

My one (professor) friend who teaches (modern) (Czech) literature has been disgusted with rich and entitled international students in recent years – she says it’s a growing trend, and a growing problem – and she’s encouraged me to speak out about it, whether to the students directly or through writing a column in a local paper or something.

Only, something like that could come off as mega-xenophobic…  Just too hard to pull off no matter how delicately you address things, you’d get so much blowback if it wasn’t anonymous.
