Gwen Stefani's Rich Girl

Specifically the line: ‘If I was a rich girl, then I’d have all the money in the world’. Richness is all relative. Compared to the average third-world resident, I am rich. Compared to the majority of the first-world, Gwen Stefani is rich. You do not need to have all of the money in the world to be classed as rich.

By the same token, if you are rich, you have a relatively large amount of money. You do not, under any circumstances, have all of it. If you did have all of the money in the world, Gwen, you would be paradoxically poor as without hard currency, people would have to revert to a primitive barter system and your wealth would be meaningless. More to the point, it is very unlikely that anyone would wish to trade food with you in exchange for your lamentable services as a 40-year-old woman dressing as a cheerleader.
