The talent for making money in every venture.
For much of his career Donald Trump seemed to possess the Midas touch.
Midas was the legendary king of Phrygia who, when granted one wish by the god Dionysus, asked for the power to turn everything he touched into gold. When he found that even his food and drink turned to gold, he begged Dionysus to take back his gift. The moral of this tale of greed is usually ignored when the term is used today.
