[Kbelicius]

How does it not mean that wealth is limited? I mean, how can you have more wealth than the value of world resources?

[BurningFrog]

Here is an example:

Oil was an annoying sticky substance until the liquid-fuelled internal combustion engine was invented in 1876. This invention turned it into the most valuable resource in the world for the next 150 years.

That invention turned useless goo into gazillions of wealth.
