However, the leaked Trump tax return said he paid $35 million.  (obviously the one year supposedly leaked was done for positive political spin)
And Tom, did Mr. Rockerfeller ever put any of his own fortune at risk by investing in new ventures or did he live off his Exxon dividends and bank salary.  
i.e. not all income or losses are equal
However, I respect Mr. Rockerfeller for his philanthropy.
May he RIP.
