Simply from a factual perspective, Varoufakis presided over the recovery of the Greek economy, not its destruction. Now you may or may not feel that's something he should get credit for, but it's a fact that he rejected EU austerity plans, and a fact that Greece's economy is improving.

Personally I think his track record is impressive, and I'd argue that helping to save an EU-level economy is at least as impressive as what Jeff Bezos has done with his life.
