Materialistic youth seem to be languishing while grateful youth seem to be flourishing.

In this study, 1,000 high school students completed measures of materialism, gratitude, academic functioning, envy, depression, life satisfaction, social integration, and absorption.

Gratitude, controlling for materialism, predicted all outcomes considered: higher grade point average, life satisfaction, social integration, and absorption, as well as lower envy and depression.

In contrast, materialism, controlling for gratitude, uniquely predicts three of the six outcomes: lower grade point average, as well as higher envy and life satisfaction.
