Whether you like it or not, somebody selling keeps most of us in a job. Mostly I’m a software developer but I’m in a role now that requires selling. The simple truth is that most people need some kind of push to get them to make a decision. Whether that’s a needs based thing as described in “buyer-pull” or a couple of little harmless manipulations doesn’t really matter in the end. As long as the customer got what they wanted it’s mutually beneficial.
And bonus: you get to keep a job sheltered away from the grotty truth of how the money is made that funds your salary.
Unfortunately my company needs sales, because other companies have sales. That's a nuclear weapon situation. Sales gives a leverage, pushes company ahead of competition. So the competition have to have sales as well.
I find this situation toxic, but that's just sad truth of the world.
