My experience as a parent to an only-child has shown me there's just zero boredom or tolerance of boredom. Any pause or void needs to be filled with something. Any time my son says "I'm bored" my default response has become "awesome", "you're lucky", "I wish I had time to be bored" along with other quips like "boredom is a life skill". Of course, I see this same phenomenon in adults as well. So my rebuttal is that most people have much more free time than they think, it's just a matter of prioritization.
