What’s the difference between the two evaluations? The answer is that one is a subjective personal argument and the other is an objective economic argument. As a credible music lover, Tom possibly sees the likes of Westlife and Boyzone (or whoever the modern day equivalents are) as lacking musical credibility, complicit in cultural degradation and producing faux-icons that are unworthy of adulation.
As a credible economist, he understands that lots of people are willing to spend money listening to manufactured pop. The economist is generally less bothered about whether someone is right or wrong, wise or unwise to like something – he or she is primarily concerned about market signals that convey information about people’s wants, needs and preferences.
The same is true of celebrities paid handsomely to endorse products – it’s a marketing trick to convey the following message: look, we’re sure you’re not convinced that this celebrity really loves the product, but if we’re willing to pay him or her all the money to say they do we must have confidence many of you will like it. On balance, the benefits of cheap fame probably outweigh the costs.
