The crisis the world went through is just an appetizer for a future one because the weaknesses that created it have not been addressed, Marc Faber, author and publisher of the Gloom, Doom and Boom Report, told CNBC Friday.

"It's a total and complete disaster and the crisis we had is just the appetizer to the big total breakdown of financial markets and of governments in five or 10 years time when the whole system goes bust," Faber told "Worldwide Exchange."

The G20 meeting is not likely to find a solution that would prevent a future meltdown, as the people who are supposed to implement the new measures are the same people who were unable to foresee this crisis, he said.

The issues of excessive leverage and the "uncontrolled, unbound credit growth," as well as the bulging deficits and interest rates at zero are not being addressed, he added.
