I think maybe he's claiming arrogance due to a phenomena I see with my oldest kid. He'll preface a comment with the phrase "No offense, but...", and then proceed to say something really offensive. It seems like your article drops that bomb, and then tries to appease us corporate folks with some ego stroking, even though we don't have the chops that consultants do.

I went from the consultant side to the corporate side about 10 years ago, so I know a little about both. What I can say is that things are rarely black and white, so much so that in this case it's a shaky assertion to base an article on (unless you were trying to start a debate). Speaking from my own experience, being a consultant was really hectic. You were expected to know everything, there was more to do than you could ever really get to, and more often than not there was not enough budget in a project for me to stick with it until the job was really and truly done. It was not fulfilling, mostly for the last reason. I found a good gig on the "other side", and went with it. The stress is there, but different. I get to see things all the way through to the end. The stress centers more around the fact that I "own" what I do more directly than I did as a consultant, and if my "customers" are unhappy, I can't just move on to the next client without dusting off my resume. The buck stops with me. What others have said about compliance and also about other areas of IT that are frequently not farmed out are completely spot on as well. It's harder to stay current on the corporate side for me, but I make it a point to do so.

I think I'd say there's too much variety out there as far as consulting and corporate IT gigs to make sweeping generalizations like those in the article. If there's anything that can be said, it's that the two roles are like apples and oranges in terms of responsibility, ownership of what you do, and the kind of stress you are likely to encounter. Not at all convinced you can pick major and minor leaguers. There are plenty of co-workers I left behind in my consulting life that I would not let touch my network if it were the last option on earth...
