My feeling is that this problem is intractable alone. We need groups working towards liberation, and societal change to support healthy work/life balance.
What that looks like in practice is that wealthy people, especially those who won the internet lottery, should start giving something back. At the most basic level, that's paying one's taxes. Beyond that, they should start setting aside ego-based goals and start accepting requests outside of their attention so that the most pressing problems facing humanity can finally get solved.
Give a billionaire $1 billion and a year later they'll turn it into $2 billion. Give one of us $1 billion and a year later a form of cancer will be cured. That's why they have the money and we don't, and why it takes so long for things to get better, if they ever do.
You thought of it 20 years ago and didn't do it, and you're considering it again now.
Instead of telling yourself it is too late to do it now, just go for it, so that in 20 years more you will be happy you planted this tree.
(Even if they are just "family" in the broader sense and not their own)
I’m rooting for you!
