"Blue-collar billionaire" Donald Trump may tap multimillionaire Mitt Romney for secretary of state, but Romney — whose net worth is about $250 million — would be somewhere in the middle of Trump's Cabinet picks, wealth-wise. Wilbur Ross, Trump's commerce secretary nominee, is worth at least $2.5 billion, according to Forbes, and Ross' nominated deputy, Todd Ricketts, is scion of the billionaire family that owns the Chicago Cubs.
