This is misleadingly bimodal. There are a ton of great "builders" out there who just aren't cut out for early stage work - they want to work on a functioning team with a well defined role and clear goals/targets.

This is really orthogonal to the problem you are pointing out, which has a kernel of truth: if the money and/or impact gets big enough you start to attract people who are primarily motivated by that. This is true at all levels.
