Why do we deem some jobs and items unworthy of payment?

BEFORE I start, I should say that the Irish Examiner website is my gateway into the world. Occasionally, though, I will look at other newspaper websites — just to see what second- and third-best look like.

And, in recent days, on one of those websites, a little pop-up window has appeared, expressing the hope that I have enjoyed my 10 free articles this month and that I can continue to read more if I pay some money.

“Aha”, I think “the game is up”. They obviously weren’t messing. Initially, I feel a sort of indignation. How dare they take away the thing I was getting for free?
