AITA for not wanting to hear about my sister's first world problems

My sister married into a millionaire family. Her husband is a CEO and my sister says she's a sahm/homemaker but are you a sahm/homemaker if you have 5 different Nannies? One for the morning, one for the evening, one for overnight. One for weekend days and one for weekend nights. You have multiple housekeepers and 4 different private chefs. Not to mention she says she only sees her kids for maybe 2 hours a day. To me that isn't a sahm. You're just an unemployed rich woman with kids. She's very Instagram heavy and posts about being rich on tiktok. I wish she would stop putting her boys on tiktok because people have commented some disgusted pedophilic stuff on things she posts with them and she says "there are pedos everyone. There's nothing I can do. I can monetize off of it." I only have contact with her for my nephews. She was venting to me about the most first world problem ever. She said her evening nannies dad died and wanted off to go to the funeral. My sister has plans and was complaining that this messes with them which her plans was to go out with friends. She was complaining that she doesn't want to give her the time off but she feels like she has the bc it just takes her making one TikTok and she would get cancelled because people hate wealthy people. She was really complaining about having to give her nanny time off because her dad died. Any good person would do that. She said she would say no if she warsn worried about her nanny getting her cancelled. I said "Kim there are people dying." She got mad and called me a cunt. Oh no. She has to spend time with her kids in the evening for a week and do rich mommy shit(literally what she calls it on Tiktok. Rich mommy shit). I just couldn't hear this nonsense
