Dopamine is the pleasure chemical, not the happiness chemical, and like any drug, dopamine crashes HARD, so the more you ride that dope train, the more you need and the worse you feel. It also affects your ability to focus, process, remember and reason, so sometimes calling younger generations stupid or addicts isn't meant as an insult. There's just no other way to say it, especially with how short people's attention spans are these days.
