Mr. Saverin (therichest.org)

It may look like Eduardo Saverin, international playboy and man of very few public pursuits, renounced his American citizenship in favor of a lesser tax bill, but that's just a coincidence, you guys. A very unfortunate coincidence. Mr. Saverin actually filed to renounce his citizenship way back in January 2011, because there's no way he could have had the slightest inkling that Facebook might go public soon, being a cofounder and all.

“I’m not a tax expert,” he told the New York Times, while refusing to offer any other explanation for why he'd agree to a move that could mean he is never allowed back into the U.S. again. “This had nothing to do with taxes," he insisted.

Okay then.

But perhaps more interesting than Mr. Saverin's arguably sketchy tax practices, is his flighty nature--and the fact that despite his sizable net worth, he has yet to choose any particular pursuit to funnel that money towards. The Times paints a portrait of a wealthy, capricious manchild, who flits about Singapore flanked by pretty ladies and swigging bottles of champagne. In some circles that might be known as swag, but in the Times piece, it translates to vaguely pathetic.

"Of all the founders, Mr. Saverin has had perhaps the greatest difficulty figuring out how to build on what is likely a once-in-a-lifetime experience," wrote the Times.

"It’s a misperception, especially the playboy,” Mr. Saverin told them. “I do have a Bentley. I do go out. I’d rather not go into personal details."

Maybe don't mention your Bentley when you're trying to convince us you're not part of the global glitterati.

Mr. Saverin is set to gain a few billion from Facebook's IPO, so perhaps he's waiting for that windfall to thrust revolutionary business ideas upon the unexpecting public. We're not holding our breath, though.
