If if a mother with three jobs can barely feed a family of four, let's be generous and say she earns 200K annually. Quite an exaggeration, but whatever. Let's say the billionaire earns 20 million a year. A massive scale-down, but again, whatever. Let's be generous again and say that the mother of three works 20 hours a week. (Yes, total between her three jobs.) for it to be fair, the billionaire would have to work 2000 hours a week. Even in such an extremely favorable circumstance for you, it's still not possible.
So can it with the "They earned their money and the rest of you always slack off" crap.
