Stefan Molyneux has explained it so clearly that even I was able to understand it. When a grifter sees his meal ticket threatened, it is an existential threat. There are people in the world who have no idea what it means to support themselves by actually being useful to other people, who regard any demand that they stand on their own feet and support themselves useful, as a mortal threat to their existence.

No conscience intervenes in the matter - it is naked self preservation and blinding fear. Doesn't excuse any of it. Does explain the psychology.
