A phrase or idiom to describe someone who feels entitled, but is blissfully unaware of the social disparity

From the ongoing Hollywood scandal over “pay for play” inscription at Universities…

It is often noticed by under-privileged students that there seems to be preference given to wealthy applicants to USA universities. The rich can afford special preparatory academies, and their children often pad their resumes with doubtful “accomplishments”.

An example…

Olivia Jade Giannulli revealed that when she was applying to colleges, she "wasn't fully aware of what was going on," and had been living in a bubble where paying a college recruiter was the norm.

"When it first happened I didn't look at it and say, 'Oh my God like how dare we do this?' I was like, 'Why is everybody complaining? I was confused what we did.' That's embarrassing to admit," she said, adding that she was a good high school student, but didn't deserve to be at USC.

“Living in a bubble” is broad, and “entitled” usually connotes a “Karen” type.

Karen is a pejorative slang term for an obnoxious, angry, entitled, and often racist middle-aged white woman who uses her privilege to get her way or police other people's behaviors.

Is there a better phrase or idiom to describe a person who lives a privileged life, and is unaware of how unjust that actually is?

Here on the Eastern side of the Atlantic the nearest I can get is they are "born with a silver spoon in their mouth".

= to be born to parents who are rich and have a good social rank; someone who is born into privilege and wealth.

The British aristocracy was popular to use silver wear when dining and the phrase is speculated to have originated from the spoons particularly because wealthy godparents had a tradition of gifting silver spoons to their godchildren when they would be christened. Source: theidioms.com

and a contemporary example:

UK politicians “born with silver spoons in their mouths, who went to private schools and elite universities” were responsible for the current impasse in parliament, but were unlikely to suffer the direct consequences of their actions, he said.

And, in my life I have always heard it used in this way, to indicate someone who enjoys wealth and privilege but does not question their right to be so fortunate.
