The example many are buzzing about right now is the billionaire investor Tom Perkins, a founding member of the venture capital firm Kleiner Perkins Caufield & Byers.

In a letter to the editor of the Wall Street Journal Perkins lamented public criticism of the “1 per cent” – and compared such criticism to Nazi attacks on the Jews, suggesting that we are on the road to another Kristallnacht.

You may say that this is just one crazy guy and wonder why the Journal would publish such a thing.

But Perkins isn’t that much of an outlier. He isn’t even the first finance titan to compare advocates of progressive taxation to Nazis.  

A thing: Reductio ad Hitlerum

And he's angry with KPCB for distancing itself from him.
