The former is the scammy type, the latter is the type we love to work with.
But the same is true in any industry. Too many of us in technology are doing the technology equivalent of 1--becoming experts in C++ or React--instead of becoming deep domain and user experts.
I despise the guy who sells extended service contracts at the car dealership. I sure as hell don't want that guy selling software work because I won't be able to complete the work profitably and I'll be dealing with angry customers who don't trust me.
To take an extreme example: Selling a starving person a meal doesn't just extract the price value, but creates it too.
You might argue that there are better or more efficient was of creating that value, but the fact that it is created is inescapable.
If you want to make a utilitarian value argument against it, you need to compare it to a real world alternative subject to scrutiny that is just as harsh, not a perfect world one.
Depends- you might not even qualify non-type-1s as sales people. Especially the type that's trying to help you get what you need, and listen to you in the process.
Do they usually come from an IC developer role?
In theory you should have better luck by walking in and saying I'll pay MSRP (thus giving them a reasonable profit) if you don't add all that other BS. In practice they won't know how to do that because nobody else does
If I could go into a dealership and trust that everyone in the building wasn't out to get me, and instead wanted to build a longterm relationship with me from sales to service, advertised the actual cost of the vehicle instead of a BS pre-fees, pre-additional markup price, then I wouldn't do that. Perhaps I'm not seeing the whole story, but as I understand it the dealerships changed their behavior first, and the customer _had_ to get more savvy as a result.
You put enough customer predatory sales practices everywhere, and you raise a generation who just doesn't trust sales staff. It doesn't have to be this way though.
I gotta be careful though, I'm dangerously close to getting on my soapbox about how difficult it is to be a sustainable lifestyle business in today's day, and how much I wish a return to that.
There is the guy at the car dealership who specializes in adding an extended service contract for your new car.
Then there's the guy who sells a software development project that lands a well qualified customer (joy to work with) and a good specification which was well estimated and price so you can complete the work profitably. Maybe you know nothing about formalwear but somebody sells you a suit you really feel good in.
