A less cynical take is that sales connects the people who need a problem solved to the people who can solve it.
A very common approach to sales nowadays is to invent a problem that someone does not have and then try to sell them your tool that fixes the problem
Or they try to map the problem you have to the problem they solve, even if they are actually quite different problems
The biggest problem that sales is trying to solve is that you aren't buying anything from them
It comes across as “everyone else’s work is trivial and low value but my, MY, work is difficult and important”. We shouldn’t be so precious.
