That's right! If everyone was as talented and hard working as J K Rowling, then we could all be millionaires by selling each other our stories about young witches and wizards.

Unfortunately, there wouldn't be any poor people left to build houses or cars, grow crops, mine minerals, work in restaurants, etc. etc.

So we wouldn't have anything to spend our money on, and we'd probably starve to death or similar. We'd die wealthy though!

It doesn't make any difference if some of the wealthy people make their money by, say, managing a ship building company. You still need some workers to actually build the ships, make the steel for the ships and so on.

The idea that everyone can be wealthy is self-evidently ludicrous to anyone who spends a few minutes actually thinking about it.
