Putting aside the payment issue, as that's a confusing one even for 'professionals' in this modern music world - I find it difficult to believe people will get much joy from something they have no talent at. More to the point, there is the opportunity cost; time is better spent on something they have more ability for, and hence will derive more enjoyment from.
Taken to an extreme, lack of talent that is disclosed in public causes people a lot of stress. Take a look at any kind of 'world's next best singer' program for many examples of this.
