Just be honest about when you've accumulated enough, I guess. If you're already sitting on a large enough pile of savings to live comfortably until you're 120 maybe it's time to retire / give back, not buy extra property.
Plan so you can live comfortably, then with the excess, fund people doing things you consider important, if they're open to contributions. Sponsor schools and community stuff.
Accumulation of wealth beyond the reasonable needs of yourself and dependents is pointless.
Full disclosure I don't have the income for this yet so I can't offer experience just opinion.

I'm sure there are all kinds of metrics and analytics available but I'm interested:
What are the "rawest" forms of user interaction that Facebook makes available to these companies?
