I haven't claimed anything but shared my experience which is that local academics rule whether it is in management of academic programs or English. I didn't read my local coworkers' master theses but plenty of email messages and heard directions for students how to write. Understandably, those facts cannot be enough for you, since you have the need to accumulate a lot of posts on the topic which will soon have the most important points lost in the jungle of trolls.

How can you claim that? Did you ever read their master theses?
