I a lot of people measure their own self worth by comparing themselves to others. For people with a job where they directly create something, usually they are proud of that thing they created. People who work in these kinds of business roles often don't actually
do anything. They have to see themselves as a necessary (and rare!) oil that enables creators. For many, it's really important to their self worth that they think, "Without me, you would be nothing. Yes, I know you can actually do the thing that you are doing, but
I am the gatekeeper."
I mean, some people think that VCs are "useless sacks of breathing meat". So when the VC in question needs to feel a sense of self worth, they need to come up with a reason that they are needed in the equation (whether justified or not). They also need to project that feeling because who will seek out a VC that's a useless sack of breathing meat. You want to seek out a VC that's the gatekeeper to riches.
You get this kind of sub-vocal interplay and posturing. I'm sure it's super stressful to the people in question. Every time they meet someone they may feel they have to justify their progression beyond meat sack level. They may feel that they have to justify it to themselves.
And interestingly, having projected their desired ego and internally swallowed their own special brand of Kool Aide, quite a few are actually convinced that they are the gatekeepers to riches and everybody else is lucky just to be in the same room.
Being human is hard.
