I don't necessarily disagree with you, but coming in with the mindset is not always natural. We don't know where the poster grew up, their education, their background, etc. It's not the worst assumption to believe that a company is going to be invested in developing you because some will and do. Sadly, the poster was not part of one of those companies.

So instead of beating them down, we should point them to a better way of thinking in a more constructive manner.
