I always advice to build their success my their self no matter what it cost,you're are nobody's responsibility everybody struggled so hard to build what the have and my some mindset of entitlement you think a portion should be automatically reserved for you,I feel such people are just lazy people who are waiting on other people to labour then they eat.
I have often time heard family members blaming other siblings for their lack of success and thats totally out of the line for me.
Leave people to help you when they want to.
