There is a direct correlation between what someone produces and what someone earns. Your two examples produced boat loads of money for a few media companies, freely determined by the viewers, the customers. If Paris Hilton makes $8M dollars a year, you can bet the house that the media company she worked for made a lot more than that off of her work product.
Don’t know that I necessarily disagree with you about a correlation between what you produce and what you earn, although what are Paris or Kim producing when they get paid for a personal appearance at a party or venue?
The article, however, was about how HARD you work. Are you saying that Paris or Kim, getting paid to go make an appearance, are working HARDER than your average bricklayer? Or, if you don’t necessarily equate HARD work with physical labor, are they working HARDER than an electrical engineer?
