The business people sure seem to make a lot more money... I can tell you that I have multiple family members that work in sales and make boatloads. My cousin spends at least 15hrs a week playing golf (something he really likes) on the company dime and getting fancy meals. That's also while making over $300k/yr. Others don't play golf but still do the lunches and meals, getting paid similarly. I'd say that this is a much easier work life than what we do...
Certainly you have non-techncal managers that are making more money than you and do you think they do more work? Certainly some do but I doubt all.
