My Security Guard Dad Holds a Fortune!

The son wants his father to take the mansion and the car. He built a company worth a billion dollars while he was still young, and he cannot understand why his father keeps refusing both and going back to his post as a security guard. The father, for his part, is puzzled by a son who works day and night for money and wonders when it will end. The argument between them comes to a head over the son's next move, a bet on new energy. The son wants in, and the father tells him plainly it is a bad idea. The son goes ahead. The market turns and the company collapses almost at once. Then the father steps in and turns the whole thing around. The son asks him whether he is the richest man there is, and the father sneers and tells him he is his dad.
