Seems like you believe it's not about where you start, it's about what you choose to do with it that matters, and sounds like you really value taking personal responsibility and working to improve your situation with your choices, rather than whinging, blaming others, making excuses, or playing the fake victim and acting entitled to the generosity of others. Sounds like you find such people really gross and disgusting, and an abomination, or at least their behavior.
I've probably already ruined your mood with my super judgy sounding comment so I'm sure you won't care what I say, but: when I read your comment i thought you were talking about leaving good people who were your family nothing, because they didn't have to suffer in the same way you clearly did.
As in: because they didn't learn to overcome the same lessons and challenges you specifically learned, they didn't deserve or earn it. As in, because, by your effort they were given an easier to start to life, you felt disgusted to make it any easier for them than you had already sacrificed to provide, and, out of some kind of resentment at having to have spend your hard earned wealth on them at all, will give them a final kick beyond the grave by gifting all your wealth to charity, as punishment.
I wasn't assuming your family was going to be egregiously, lazy, ignorant little white pricks, born in the lap of luxury and grifting off their benevolent wealthy relatives, like I'm sure you probably think I am.
How do you think people should accomplish raising their kids right?
