If you want to counteract this tendency, consider getting them into (competitive) sports. Nothing will work right away, they will have to „grind“ (train/practice) a lot, failures are all but certain; but hard work and perseverance get rewarded, and the successes are all the sweeter. As a young guy who has had a modern and easy childhood not unlike the one you describe, many of my most cherished memories come from competing in a sport.
