If you don't want to change the world, and you don't have a concrete plan for doing so, then possibly not. If you do want to change the world, it means you have to comprehensively persuade perhaps ten or twenty fewer people of equivalent net worth than you would otherwise have to. My impression is that next to nobody wants to change the world earnestly enough to make inroads in either persuasion or fundraising. The pity of it is that this is also true for the vast majority of people who have managed to become very wealthy by their own efforts - they have no idea what to do with all that money other than keep on trucking with the process that's making it. See the general flailing around for by-the-numbers Big Charity, for example, among those with enough wealth to be brand names.
