On average, intelligent people are more productive
How are you defining "productive"?
What is your proof of this claim?
Intelligence would not be so highly valued if it did not make people more productive. Here is a paper documenting my assertion.

General Mental Ability in the World of Work: Occupational Attainment
and Job Performance

The psychological construct of general mental ability (GMA), introduced by C. Spearman (1904) nearly
100 years ago, has enjoyed a resurgence of interest and attention in recent decades. This article presents
the research evidence that GMA predicts both occupational level attained and performance within one’s
chosen occupation and does so better than any other ability, trait, or disposition and better than job
experience. The sizes of these relationships with GMA are also larger than most found in psychological
research. Evidence is presented that weighted combinations of specific aptitudes tailored to individual
jobs do not predict job performance better than GMA alone, disconfirming specific aptitude theory. A
theory of job performance is described that explicates the central role of GMA in the world of work.
These findings support Spearman’s proposition that GMA is of critical importance in human affairs
