Don’t worry, they’d still be doing just fine.

That’s not to say the uber wealthy wouldn’t get torched by Elizabeth Warren’s tax plan, but even if her proposal were in place for decades, the fortunes of men like Amazon’s AMZN, +2.49% Jeff Bezos and Microsoft MSFT, +2.27% founder Bill Gates would still be intact, according to TaxJusticeNow.org, a website founded by UC Berkeley economists Emmanuel Saez and Gabriel Zucman.

In fact, here’s a look at what the net worth of these guys would be today if Warren’s plan to levy a billionaire tax had been in place since 1982:

As you can see, Gates would be down to his last $42.2 billion, Bezos would have less than $100 billion to his name and Berkshire Hathaway’s BRK.A, +0.43% Warren Buffett would have to get by on just $34.9 billion.
