Someone said, "sell emotional experiences and features". You said something to the effect of "eh, maybe that works in your market". Here's where I cut in: bzzt! It works in virtually all markets.
Even in buy-by-committee enterprise sales, there are emotional appeals that will give you an edge.
A fun exercise: look at the most successful, best marketed products in a variety of fields, and spot the emotional elements. Start with Github.
Then, again, you managed to drag a huge thread out of me based on my emotional reaction to your (frankly offensive) "Bzzt" so maybe you're right for "most" markets.
1. The business man from the city that buys a small piece of land (40 - 60 acres) and cash rents it out. Now you might say that's greed. He's looking to make more money and is greedy pushing the family farm out and renting to the big corporate farmers. You're wrong though. He bought the small farm to brag about it at cocktail parties. That's why all these business types own small chunks of land in rural areas. That's an emotional reason to own it.
2.Imagine a company that allows you to out source your life. One might say, "If I can make $100 an hour free lancing, then I should out source all tasks that I can for less than $100 an hour" and you would argue this is logical. But the real reason someone would want to outsource the laundry, and all aspects of their life is purely emotional. They can then go brag about to all their friends how perfect of a life they have because they don't have to do any crappy work. That's why people making $35 an hour are paying $50 an hour to have the crap done they could do themselves.
If you damage the emotional part of the brain, you are unable to make decisions. You can reason all day long and compare and contrast, but you can never decide.
I wouldn't be surprised if the emotional value that the guys you run into is how they can brag at cocktail parties or to their business associates how they screwed over some computer science graduate and that they used their Harvard MBA to do it.
I'm not trying to argue with you now; just extending my point.
Isn't that the basis of all voluntary transactions?
