The lower levels of Maslow’s pyramid reflect material well-being. But material abundance is not itself the cause of anomie and angst. Rather, ancestral, evolved solutions to lower-level problems also tended to contain solutions to higher-level problems as well. As these ancestral solutions are made obsolete by solutions that are more efficient on the material level, the more ineffable, higher-level problems they solved present themselves anew. Simple abundance of food is not the cause of obesity, but rather the loss of carefully evolved ancestral diets. Our ancestors found it easy to get to sleep because they were tired from intense physical activity; we often find it a challenge to get to sleep because modern solutions to material problems do not include physical activity. We are lonely and bored not because of material abundance simpliciter, but because the specific cultural patterns that have reproduced themselves to produce material abundance have whittled away the social and psychological solutions that were built into old solutions to material problems.
