It's not that we're too busy. It's that we're too busy without purpose. What's the point of being busy when it doesn't proportionately translate to having our needs met?
We have more abundance than ever before in all of human history, and yet we work harder than hunter-gatherers just to feed ourselves, and we have less leisure time than they did. We work more hours per day and have fewer days off per year than medieval serfs. And for what? What's the purpose? So some asshole who was born on third base can buy another mansion?
