With Facebook founder Mark Zuckerberg’s announcement that he will be giving away 99 percent of his Facebook stock, he is poised to join the legions of controversial moguls who have ensured that a legacy of generosity overshadows their earlier reputation for rapacity—Frick, Carnegie, Gates, Zuckerberg. It may be heartening to see, for instance, that he has joined elder billionaires like Michael Bloomberg and Bill Gates in funding green energy.

But there is also something unsettling about a world in which we seem to depend more and more heavily on billionaires to set national and global priorities. (The Gates Foundation, Jacobin recently reported, exerts what amounts to a veto power over the World Health Organization.) The irony mounts further when such gifts come in the name of, as Mr. Zuckerberg puts it, “advancing human potential and promoting equality.” The potential doesn’t seem very equally distributed.

I’m not sure if he’s an America reader, but I have some ideas about how Mr. Zuckerberg’s stock might better advance the mighty causes to which he seeks to dedicate them than the grants, investing and lobbying (via an LLC, not a conventional charity) he has thus far alluded to. See what you think:

First, the stock could go back to the Facebook users who made it valuable in the first place. As I have noted here before, Facebook’s business model depends on gathering, mining and selling the personal information that its users post on the platform. That includes our networks of relationships, our photos, our worries, our milestones, our passions and our preferences. It’s barely understood what exactly Facebook knows about us and how, except that it’s a lot. This is part of what has made Mr. Zuckerberg so controversial, and rightly so; early on, he referred to his users as “dumb” (followed by a word even more insulting) for trusting him with such data. What if, rather than papering over that controversy, he could resolve it at the root?

Consider what it would mean if a substantial portion of Facebook stock were held in a trust that acts on behalf of the platform’s users. (This is a model I’m borrowing from the employee-owned John Lewis Partnership in the United Kingdom, explained in Marjorie Kelly’s extraordinary book Owning Our Future.) Users could then vote on what positions the trust should hold at shareholder meetings, and it could distribute dividends based on the stock’s value back to users, or reinvest them by buying more ownership in the company. The trust, therefore, would have a dual incentive: to protect user interests and privacy in Facebook’s business model, and to ensure that the company remains solvent.

Second, the stock could be placed in a fund for distributing an equal, universal income. Around Silicon Valley these days, there is a growing appetite for the idea of a regular, unconditional check for everyone, mostly due to anxieties about a coming wave of unemployment by automation. (I’ve argued that there are reasons in Catholic social teaching to support universal income as well.) What if Mr. Zuckerberg were to get this started for real? For the whole world?

Even his $45 billion worth of stock would amount to only one payment of just over $6 per human being. This would mean more in some parts of the world than in others—an automatic act of redistribution—but it still wouldn’t be much. Mr. Zuckerberg’s fund, rather, would have to pose a challenge to many more wealthy individuals and governments to dive in as well. The challenge would be an interesting one: “Do you really know better what to do with all that money than the collective wisdom of everyone on Earth combined?”

Even a little bit of income spread out across the whole planet might make more of a difference than we think. If most of the world’s leaders are gathering in Paris right now over just a few degrees Celsius in average temperature, maybe just a few dollars in the hands of everyone could change the world, too.
