This is a great example because it shows just how relative "wealth" is, and makes the thought experiment accessible to anyone in a first-world country. It's just my conjecture, but I don't think most billionaires "don't care about $1000". The few people I've met with a net worth over $100M are sharp bargainers. I think the view that "they won't miss $1000" or "why would they care" is a fundamental misapprehension of the psychological make-up of wealthy people that's commonly held among people who don't have a lot of money. (And so when the wealthy do notice and care, the explanation would be that they must have an axe to grind).
