The usual kulak/petty burshwá dipshit who "runs the family business" of leeching surplus value and sending some emails is usually proud of it, leave alone the shitstains with 4 surnames and zero heterozigous loci.
Same with PMCs in overpayed jobs, usually saying "yeah I got this job thanks to my uncle/frat top"
But then mediocre overvalued "artists" piss and moan about their daddy owning Sony not being a big deal in their astroturfed careers.
Why? Some people do end up actually liking their music, so who cares if they didn't have to audition a million times and waste their own few money playing virtually for free in shitty bars?
Even those open nepo babies like to pretend that their dad just noticed their exceptional talent or something, but they are certainly less ashamed of it.
The reason might have to do with the (historical) identity of the profession. If most artists etc were in recent history the first of their family to do the job, and it didn't look like they could start a dynasty, they would naturally develop an ideology of independent merit being what matters. In comparison, in industries where most people likely inherited the job and were looking to give it as inheritance, an ideology of dynastic might being important would tend to prosper. These ideologies would then spread through shared social circles even to the minority who were of the less common origin.
Once the idea of how a person of your identity should be sets in, it is easier to just start genuinely believing you are also that way, even if it is clearly not true. Then someone mentioning your connections becomes an insult to your identity, which people generally do not enjoy.
