As to the pursuit of happiness, Plato and Aristotle do not happen to work explicitly with this felicitous expression. Nevertheless, their way of thinking about virtue as the mean between the extremes of over-doing something and under-doing it seems to hint that we should avoid insatiable pursuits because by definition we would be over-doing whatever our pursuit is.
It remains then for us to figure out a way of thinking about happiness so that our pursuit of happiness does not become an insatiable pursuit, but a manageable pursuit that can be reasonably satiated.
But Plato and Aristotle did not live in our American capitalist economy, which appears to be based on a kind of economic insatiability. In his perceptive review essay in COMMONWEAL MAGAZINE online ("Less, Please: Capitalism and the Good Life") about Robert Skidelsky and Edward Skidelsky's book HOW MUCH IS ENOUGH? (2012), Gary Gutting, who holds the Notre Endowed Chair in Philosophy and who writes columns occasionally in the New York Times, sums up the Skidelskys' view of the economic insatiability of capitalism as involving "the intrinsic drive for increasing production (and therefore profits) without limit."
In the Skidelskys' view of capitalism, we Americans today are little cogs in the big capitalist economy, which seems to favor the 1% at the top more than the 99%.
For the sake of discussion, I will go along with the Skidelskys' characterization of capitalism as involving economic insatiability. In the short-term, the capitalist economy does drive toward increasing production and profits. However, as everybody knows, in the long-term, entire businesses come and go. For example, in my lifetime the production and marketing of personal computers came into existence. For this reason, I tend to favor Joyce Appleby's way of characterizing capitalism as relentless revolution. See her book THE RELENTLESS REVOLUTION: A HISTORY OF CAPITALISM (2010).
But does it make any difference if we use the Skidelskys' characterization of capitalism or Appleby's?
The Skidelskys work with the supposed parallel between the economic insatiability of capitalism and the apparent insatiability of individual desires of people who grow up and work in a capitalist economy. But I would interpret the apparent insatiability of individual desires of people who work in a capitalist economy as showing their under-development of the virtue of moderation as Plato and Aristotle understood this virtue -- as the mean between the extremes of over-doing something and under-doing it. They may also suffer from an under-development of courage to moderate their desires. In other words, people who grow up and work in a capitalist economy are free to examine their own tendencies and to cultivate the virtues of moderation and courage in their lives.
As a thought experiment, I would suggest that we use Appleby's characterization of capitalism as involving relentless revolution, but then shift our attention to the people who grow up and work in a capitalist economy. But once we make this shift in our characterization of the capitalist economy, then we no longer have a reason to focus on apparent insatiable desires. Instead, the apparent problem would then presumably be the relentless revolution in our desires. But this apparent new problem would require another way of addressing the apparent problem.
