Try hard to separate that which comes out of (understandable) envy, and what is truly "objectionable" behavior on your sibling's part. You mention nannies and cleaning help. Nothing is wrong with that and most people would do it to if they could. You mention having family gatherings in their house. Are they truly "demanding" it? Or are they offering their home because it has more space? Have they really said no to having gatherings at your parents' house?
If you really got together frequently and now you do not, I can see why that is hurtful? Do you invite them to things?
I'm not trying to judge you. In struggle with my feelings toward my brother. Most of it is really routed in personality traits he already had, just slightly exaggerated because of the money.
This.
