Apparently Akshay won't pay $2800 for a training class. That's fine. But many will. I'm not one of them since I have an engineering degree and feel that a big part of my professional skills is the ability to learn new technologies quickly from books, code, the web, etc.
I also know that good teachers tend to be undervalued. People who are not good teachers have no concept what it means to be a good one, even though everyone is a "teacher" on occasion.
In a similar vein, my wife is a book author, and a professional journalist. She writes for Nature, Scientific American Mind, Nat Geo and other pubs. I have written published articles too. But Josie's writing is superior to mine and to most other people's who are not authors and journalists. Even though we all do plenty of writing.
My point: don't throw stones, we all live in glass houses.
Many people only do well with an auditory style of learning. They need a human teacher. (Google for "learning styles auditory visual kinesthetic" to learn more.) Others want the teacher/student interaction. They'll appreciate the class. If they don't like the pricing they'll find a different class.
I like capitalism. If the class succeeds then it was a good idea, including the pricing. I wish the teachers good success on their venture.
