Demand is pretty inelastic for a course, especially if the company is paying for it. I believe that charging at lesat $400 is the sweetspot, volume decreases (so does customer requests) and profits skyrocket.
I understand this knee-jerk reaction, but please don't judge engineers by what they post on HN. This place is... odd. (as I'm sure you know!)
If I formed my opinion only from HN, I'd think most engineers love: big-tech, advertising, electric cars, Apple, tech-enabled tracking (autos, web, cell-phone, watches, exercise machines, music players - it's ok if business profits!), and tend toward self-righteousness, narcissism, and virtue-signalling.
Of course, most of us are just living our lives and trying to get by. I don't know where this self-important insufferable attitude comes from, but I suspect it's a few folks who are very noisy. Most 'normal' people don't spend much time posting to sites like these, so there is a selection bias. Sadly, I also suspect that this attitude is an advantage in today's environment. It is a mirage of self-confidence, and telling the two apart can be very hard (especially for a potential employer).
Hi! Systems engineer for two decades now. I have a deep respect for philosophy, natural medicine, photography and the environment. I suspect many other engineers would have interests outside of their profession.
You seem to think that the meaning of "STEM" includes anything that anyone applied the word "science" to. But no, the "science" part is precisely the "hard" sciences. E.g. psychology, economics and theology aren't included in STEM.
Sarcasm aside, not all natural sciences are treated equally. There are differing attitudes towards astronomy, oceanography, and climatology, for example.
There are plenty of categories of human for which this community would not stand for an overly broad, coarse generalization like that.
Personally I'm not even convinced your claim is effective as a prejudice. What I'll concede is many engineers I've met seem to be harsher than average on pseudoscience och some varieties of manipulative lies, but that's to be expected as they have distinguishing knowledge for such things to clash with.
