It diminishes the accomplishments of entrepreneurs, and the sacrifices they've made. If they only have large equity stakes in the companies they founded because they're "privileged" it casts them as undeserving of the wealth they acquired.
Ok. And what's the harm in that?
Isn't it self-evident? It harms their standing and reputation, in being cast as in possession of wealth they are not morally entitled to. It's defamation.
Privileged =/= undeserving
Can you show an example of damage done by this sort of "defamation"?
