Warren Buffett speaks onstage at the FORTUNE Most Powerful Women Summit on October 16, 2013 in Washington, DC. Paul Morigi/Getty Images for FORTUNE Warren Buffett isn't sure that Greece leaving the eurozone would be such a bad thing.

"I've thought the euro has structural problems from the moment it was put in, which does not necessarily mean it will fail," Buffett said in an interivew with CNBC's Becky Quick on Tuesday.

Buffett added that it is not "ordained" that the euro have the same members in the future that it has today.

It is, however, ordained that the euro's members will need to have what Buffett called

"compatible management" of their economies, adding that it might not be such a big deal if Greece eventually leaves the economic bloc. "The Germans are not going to fund the Greeks forever," Buffett said.

"The euro is not dead, and may never be dead," Buffett said. "But it can't live with people going in dramatically different directions."

The discussion on Greece was spurred by Quick asking Buffett about comments regarding Greece from Berkshire vice chairman Charlie Munger, who last week said that you can't "vote yourself rich" and said the current Greek solution is "idiocy."

Greece is currently in the middle of some touch-and-go negotiations with its European creditors over what reforms its government will enact as part of its bailout deal.

And as for whether Greece leaves the euro or not, Buffett said he has no idea.

"Maybe Charlie does," Buffett said.
