OK, but what about the opposite: what is the value of pretending to be rich when you are not? I mean, sure you can probably get a free pizza slice here and there, but what can you actually do?
Pretending to wealth is a con probably as old as money itself. Just imagine: you convince a lot of people that you're a billionaire who's lost your wallet. What can you get out of those people just by the promise you're good for it?
