Being pleasant is not in opposition to ability to think or creativity. You can be both and world is not fair.

I agree. Being pleasant is probably a mix of having a good dose of the agreeableness and extroversion personality traits. Both of which are uncorrelated to creativity and IQ, other two traits.

I know, but the possibility of getting rich is a nice booby prize for the unlikeable and unattractive.

It’s definitely not impossible. You probably won’t have an easy time if you’re someone who requires the approval of a lot of people, for example, being a public figure or exploiting your image.
