He is crazy and so is Klaus Schwab. Two Jews who watch the Nazis murder most Jews in Europe while living under Nazi rule. That kind of experience warps a child and probably makes them hate themselves subconsciously. The "cleansing" destruction they pursue is a manifestation of that tortured spirit.

I knew a wealthy man who realized he was going to die, and he became angry because it became obvious that he could not buy his way to health and longer life. He vilified everyone around him and began to punish others with his resources. Sound like George Soros? It wasn't, but Soros may be cut of the same cloth.

At his age (92) I'm pretty sure he knows mortality is creeping very nearby.
It will be interesting to see how his 4 sons and his daughter carry on his legacy after he dies.
