If moving up the hierarchy of needs causes more worries (like environmentalism:
In 1943, the American psychologist Abraham Maslow wrote a seminal paper called “A Theory of Human Motivation.” In it he introduced the theory that humans have a “hierarchy of needs,” a deceptively simple concept that many of us can still remember seeing as a multicolor pyramid in our high school social studies classes. At the bottom of the pyramid there were the basic material needs: food, shelter, and security. Above those were esteem, belonging, and status needs, and above them were “being” needs, such as purpose, self-creation, and fulfillment. Maslow argued that once we have met the lower material needs, new and higher needs emerge that demand our attention. Sociologists today describe these higher needs as “postmaterial,” since they emerge only after our basic material needs have been met.
then it's evident that the way to get rid of these sources of angst is to simply move down the pyramid.
