Generally I wouldn't respond to a "blunt sarcastic asshole" but, I'm going to, because I think what you're saying is a little unfair.
I don't want to make our engineers sales people, what I want them to do is identify potential areas where we could solve a business problem for a customer with IT and then advise the customer to that extent.
I'm not looking to cash in on their credibility or burn that goodwill with customers, I just want them to keep their eyes open for potential opportunities instead of just being out there fixing things.
And to further clarify, I'm actually an engineer by trade and I've been there in their positions before, I've moved on to manage a team and then manage a division and I'm trying to work out how I can help the engineers to make a little more money, by helping us make a little more money.
I try not to get too involved in these things, but your blunt sarcasm is quite useless. I'm not really sure how you got insightful for this post.
